Pin Name PXCK Pin Number 95 Value TTL Description Pixel Clock Input. PXCK is a clock signal that period is twice the sample rate of the pixel data. The operating range is 20 to 30 MHz. The clock is internally divided by 2 to generate the internal pixel clock, PCK. PXCK drives the entire TMC2193 except the asynchronous microprocessor interface. Master Chip Reset. When LOW, All outputs are tri-stated and the internal state machines and control registers are reset. At rising edge of RESET, all outputs are active, the preset values will be loaded into the control registers and the internal states machines start to operate. Vertical Sync Input. When operating in slave, Genlock, or DRS-Lock the TMC2193 will start a new vertical field with each falling edge of VSIN that is coincident with HSIN. Field Identifier. Field Identifier outputs the current field number. For all video standards the field identifier will cycle through the eight counts. Horizontal Sync Output. The alignment of HSOUT to the pixel data port or DCVBS port is controlled by control register TSOUT. Vertical Blanking Interval Line Identifier. LINE identifies the current line number for the first 31 lines. If the line count is greater than 31 then LINE is 11111b. The first line with a vertical serration is considered to be line 0. Pixel Data Control. When PDCDIR = LOW: At a rising edge, The next pixel starts a controlled ramp of the PD data. At a falling edge, the pixel prior is the last PD used in the ramp. The rising edge is determined by the PDCCNT control register, the falling edge of PDC is determined by the horizontal timing registers. When PDCDIR = HIGH: PDCIN is used to override the internal PDC. When HIGH, the internal PDC controls the blank and unblank window. When LOW, the video remains blanked regardless of the internal PDC. All edges have the same ramp control as the internal PDC.

Functional Description

Control Registers for this section Address 0x05 0x05 0x06 Bit(s) 7 6-4 0 Name D1OFF INMODE TSOUT
Demuxing of multiplexed data streams depends on which synchronization mode the encoder is operating in. For slave and genlock modes the falling edge of HSIN must be LOW prior to the CB data in order to demux the data correctly. For master mode synchronization the falling edge of HSOUT must be LOW prior to the Y data in order to demux the data correctly. Finally, in 656 mode the demuxing of the data stream is determined by the TRS codes, the first sample after the TRS is considered a CB sample of the CB Y CR YI packet. The control register D1OFF controls the formatting of the incoming luminance data at the pixel data port. When D1OFF is HIGH a blanking level of 6410 is subtracted from the luminance and when D1OFF is LOW the incoming the pixel data is passed through. The inversion of the MSB's on the CB and CR components is controlled by the INMODE control register.
The TMC2193 supports both RGB and YCBCR component sources on the pixel data port. For RGB sources the TMC2193 will accept a 24 bit RGB source with a sample rate of 4:4:4. YCBCR input sources are supported in 10 bit 4:2:2, 20 bit 4:2:2, 20 bit 4:4:4, and 24 bit 4:4:4. In the 4:2:2 cases the color difference components are linearly interpolated to 4:4:4 internally.

Inherent in all CRT displays is a non-linearity between the voltage applied to the electron guns and the CRT phosphor brightness. Traditionally this non-linearity, gamma, is compensated at the camera. However, many sources today are mixed in the digital domain and do not contain any gamma correction. For this reason the TMC2193 contains optional gamma correction process. The TMC2193 contains two independent gamma circuits, one for the Green data path and the other for the Blue and Red data path. Each gamma processor has two (2) gamma compensation curves, one for NTSC and one for PAL, that can be applied to the incoming video data. The formulas for the gamma curves are: PAL: Y=X NTSC: Y = 4.5 * X Y = 1.099 * X1/2.22 - 0.099

The color space matrix (CSM) has four modes of operation, which are controlled by CSMFMT. The CSMFMT bits configures the color space matrix to produce the desired outputs from the input source. The inputs for the CSM can be either RGB or YCBCR. In all four modes YUV for the composite generation will always be one set of component outputs of the CSM. The other set of components outputs can be either RGB or YPBPR. * CSMFMT = 00 , YCBCR input source with YUV and YPBPR outputs.

Synchronization Modes
Control Registers for this section Address 0x06 0x06 0x06 Bit(s) 5-3 1 0 Name MODE TOUT TSOUT
CCIR656
The TMC2193 derives all synchronization from the embedded TRS (timing reference signals) information. Blanking of selected lines is determined by the v bit of the TRS. However the control registers VBIENx can override and blank the active video portion of VBI lines regardless of the state of the v-bit.
Genlock
The TMC2193 offers a variety of synchronization modes; these are master, slave, genlock, 656 mode, and DRS-Lock. In master mode, the TMC2193 generates its own timing and the synchronization is supplied externally by HSOUT and VSOUT signals. In slave and genlock modes the TMC2193 derives its timing from the input pins HSIN, VSIN. In 656 mode the timing is driven by the synchronization codes embedded into the data stream.
Master
The TMC2193 is driven by the input synchronization pins HSIN and VSIN. When the falling edge of HSIN and VSIN occurs at the same rising edge of PXCK the TMC2193 will start a new field.VSIN can be either a traditional pulse or the MPEG style field toggle. In both cases the TMC2193 will flywheel through fields 2, 4, 6, and 8 synchronizing only to fields 1, 3, 5, and 7. The TMC2193 collects GRS data and resets its subcarrier phase and frequency to the data embedded in the GRS stream. The GRS detection occurs only on the CBVS port.
DRS
The TMC2193 drives the output pins HSOUT and VSOUT to synchronize the incoming video. A new color frame starts at the rising edge of RESET. The encoder always starts at the 1st vertical serration in field 8 and will freerun the field and line sequence. The control register bit SRESET can be used to synchronize the start of the field and line sequence in master mode by resetting the FVHGEN state machine. Output synchronization signal VSOUT can operate in a traditional sync mode or in a MPEG style field toggle mode.
Slave
The TMC2193 is driven by the input synchronization pins HSIN and VSIN. When the falling edge of HSIN and VSIN occurs at the same rising edge of PXCK the TMC2193 will start a new field.VSIN can be either a traditional pulse or the MPEG style field toggle. In both cases the TMC2193 will flywheel through fields 2, 4, 6, and 8 synchronizing only to fields 1, 3, 5, and 7. Subcarrier phase adjustment is determined by the DRS data. The DRS detection can occur on either the CBVS port or the pixel data port.

Propagation Delay
The propagation delay from the pixel data (PD) input to the D/A output is 64 PXCK's. Figure 8 shows the propagation delay for both master and slave synchronization modes. For CCIR656 data streams, pixel 736 (pixel 0 in Figure 8) is the midpoint of sync and is 32 PXCK's (24 PXCK's in PAL) after the EAV TRS.

Pixel Data Control
The pixel data control has two modes of operation, as an input or as an output. The mode of operation is determined by the PDCDIR control register. When PDC is an input the internally generated PDC is ANDed with the PDC pin. This allows the user to blank any active video regions. When PDC is an output, the internally generated PDC is the output for the PDC pin. The internal PDC control will toggle to a logic HIGH at the pixel specified by PDCNT and toggle to a logic LOW four pixels prior to the end of the active video region. The starting point and ending point of the active video region (VA) are determined by the control registers 10h to 1Fh. When PDC is used as an input, the sloped edge of the active video region will occur on the next four pixels following the toggle point.
The content of VBIENFx[4:0] selects the first line to contain an active video region in each field, all subsequent lines for the remainder of the field are active. To blank an entire field, the user zeroes the VBIENFx[4:0] control register. In CCIR656 slave mode, the user can selectively blank any enabled line by setting its TRS V bit HIGH. For 525-line systems, NTSC line numbering is employed, with the first vertical serration starting on line 4. PAL line numbering is used with 625-line systems, with each field's line 1 being the start of the first vertical serration. Any line(s) enabled by the closed caption control are automatically unblanked for the closed caption waveform, irrespective of the corresponding values of VBIENF. Table 6.

Edge Shaping
The TMC2193 has three modes of sloped edges on the active video region and are controlled by PDRM control register.
Slope type at PDC (LOW) The following four pixels have the weighting of 1, 7/8, 1/2, and 1/8 for NTSC and 7/8, 5/8, 3/8, and 1/8 for PAL. The fifth pixel is sampled and scaled 1, 7/8, 1/2 and 1/8 over the next four pixels for NTSC and 7/8, 5/8, 3/8, and 1/8 over the next four pixels for PAL. Slope is off, edge control is dictated by the PD stream to active video end

Horizontal interval timing is fully programmable and is established by loading the timing registers with the duration of each horizontal element. The duration is expressed in PCK clock cycles. In this way, any pixel clock rate between 10 MHz and 15 MHz can be accommodated, and any desired standard or non-standard horizontal video timing may be produced. Horizontal timing parameters can be calculated as follows: t = N x ( PCK period ) = N x ( 2 x PXCK period ) where N is the value loaded into the appropriate timing register, and PCK is the pixel clock period. When programming horizontal timing, subtract 5 PCK periods from the calculated values of CBP and add 5 PCK periods to the calculated value for VA. The control register HALFEN enables the 1st half line (UBV) on line 283 for NTSC, PAL-M and line 23 for all other PAL standards when it is LOW.

ming, any pixel rate between 10 and 15 Mpps can be accommodated, and any desired standard or non-standard vertical video timing may be produced. Like horizontal timing parameters, vertical timing parameters are calculated as follows: t = N x ( PCK period ) = N x ( 2 x PXCK period ) where N is the value loaded into the appropriate timing register, and PCK is the pixel clock period. The vertical interval comprises several different line types based upon H, the Horizontal line time. H = (2 x SL) + (2 x SH) [Vertical sync pulses] = (2 x EL) + (2 x EH) [Equalization pulses]
Vertical interval timing is also fully programmable, and is established by loading the timing registers with the duration's of each vertical timing element, the duration expressed in PCK clock cycles. In this way as with horizontal program-

Notes: 1. XBP, VA, VC, and VB are 10 bit values. The 2 MSBs for these four variables are in Timing Register 2D. 2. EH and SL are 9 bit values. A most significant "1" is forced by the TMC2193 since EH and SL must range from 256 to 511. EH and SL may be extended to 767. Only the eight LSBs are stored in Timing Registers 29 and 2A. 3. Every calculated timing parameter has a minimum value of 5 except EH and SL which have minimum values of 256.
Vertical Timing
The vertical timing is controlled by the FORMAT control register, which dictates the field and line sequence.

NTSC Subcarrier
For NTSC encoding, the subcarrier synthesizer frequency has a simple relationship to the pixel clock period, repeating over 2 lines: The decimal value for the subcarrier phase step is: 455 2 32 FREQx = -------------------------- x 2 pixels line Where the number of pixels/line is: PXCK Frequency pixels line = -----------------------------------------H Period This value must be converted to binary and split into four 8 bit registers, FREQM, FREQ2, FREQ3, and FREQL.
PAL Subcarrier
The PAL relationship is more complex, repeating only once in 8 fields (the well-known 25 Hz offset): ( 1135 4 ) + ( 1 625 ) 32 FREQx = -------------------------------------------------- x 2 pixels line This value must be converted to binary and split as described previously for NTSC. The number of pixels/line is found as in NTSC.
PAL-M Subcarrier
Subcarrier Programming
909 4 32 FREQ = -------------------------- x 2 pixels line SYSPHx establishes the appropriate phase relationship between the internal synthesizer and the chroma modulator. The nominal value for SYSPHx is zero. Other values for SYSPHx must be converted to binary and split into two 8 bit registers, SYSPHM and SYSPHL. Burst Phase (BURPHx) sets up the correct relative NTSC modulation angle. The value for BURPH is: BURPHx = SYSPHx This value must be converted to binary and split into two 8 bit registers, BURPHM and BURPHL.
The color subcarrier is produced by an internal 32 bit digital frequency synthesizer which is completely programmable in frequency and phase. Separate registers, FREQx, SYSPHx, BSTPHx, are provided for phase adjustment of the color burst and of the active video, permitting external delay compensation, color adjustment, etc. FREQx is the subcarrier phase step per pixel and SYSPHx is phase offset at field 1, line 1 (line 4 for NTSC), pixel 1.

Subcarrier Synchronization
There are 5 modes of subcarrier synchronization in the TMC2193, freerun, subcarrier reset, Genlock, DRS-lock and Ancillary Data Control (ANC). * Freerun
At the rising edge of RESET the DDS starts to generate the subcarrier reference and will continue to freerun the subcarrier. When setting the control register DDSRST is HIGH, the TMC2193 will reset the DDS to the SYSPH value on the next field 1, line 1 (line 4 for NTSC), pixel 1 occurrence and will reset this bit to be LOW. This allows the encoder to start with the correct SCH relationship. The phase of the subcarrier reference will drift over time since a 32 bit accumulator has a error of 0.5 Hz when generating the subcarrier reference for NTSC 13.5 MHz. * Subcarrier Reset
the TMC22x5y. The TMC22x5y produces a decoder reference signal (DRS) which contains field identification, PALODD status, relative phase and relative frequency of the composite or S-video input. The DRS is sampled on either the CVBS bus or the PD port, depending on DRSSEL, 60 PXCK's after the falling edge of HSIN. The phase and frequency values are used to update the DDS on a line to line basis, thus synchronizing the subcarrier to an external composite reference. * Ancillary Data Control (ANC)
Subcarrier synchronization in ANC mode is covered in the Ancillary Data Control section of this data sheet.
SCH Phase Error Correction
At the rising edge of RESET the DDS starts to generate the subcarrier reference and will reset the DDS to the SYSPH value every field 1, line 1 (line 4 for NTSC), pixel 1 occurrence. This enables the encoder to maintain the proper SCH relationship. * Genlock
SCH refers to the timing relationship between the 50% point of the leading edge of horizontal sync and the positive or negative zero-crossing of the color burst subcarrier reference. SCH error is usually expressed in degrees of subcarrier phase. In PAL, SCH is defined for line 1 of field 1, but since there is no color burst on line 1, SCH is usually measured at line 7 of field 1. The need to specify SCH relative to a particular line in PAL is due to the 25 Hz offset of PAL subcarrier frequency. Since NTSC has no such 25 Hz offset, SCH applies to all lines. The SCH relationship is important in the TMC2193 when two video sources are being combined or if the composite video output is externally combined with another video source. In these cases, improper SCH phasing will result in a noticeable horizontal jump of one image with respect to another and/or a change in hue proportional to the SCH error between the two sources. SCH phasing can be adjusted by modifying BURPH and SYSPH values by equal amounts. SCH is advanced/delayed by one degree by increasing/decreasing the value of BURPH and SYSPH by approximately B6h. An SCH error of 15o is corrected with SYSPH and BURPH offsets of AAAh.
The Genlock mode allows the TMC2193 to lock to a composite reference when used in conjunction with the TMC22071A Genlocking Video Digitizer. The TMC22071A produces a genlock reference signal (GRS) which contains field identification, PALODD status, relative phase and relative frequency of the composite reference. The GRS is sampled on the CVBS bus 60 PXCK's after the falling edge of HSIN. The phase and frequency values are used to update the DDS on a line to line basis, thus synchronizing the subcarrier to an external composite reference. * DRS-Lock
The DRS-Lock mode allows the TMC2193 to lock its composite output to the decoded composite or S-video input of

Burst Envelope
The TMC2193 includes the ability to adjust the burst amplitude and the shape of the burst. The Control Registers BRSTFULL, BRST1 and BRST2 hold the magnitude of the burst vector. BRSTFULL is the maximum amplitude of the burst vector. BRST1 and BRST2 determine the intermediate values of the burst vector for the burst envelope shaping. A 5 pixel burst envelope shaping occurs at the rising and falling edges of burst. At the rising edge of burst the next 5 pixels have the following weighting; BRSTFULL - BRST1, BRSTFULL - BRST2, BRSTFULL/2, BRST2, and BRST1. At the falling edge of burst the next 5 pixels have the following weighting; BRST1, BRST2, BRSTFULL/2, BRSTFULL - BRST2, and BRSTFULL - BRST1. With this flexibility the user determine the shape, amplitude and width of the burst signal.

Color-Difference Low-Pass Filters
The chrominance portion of a composite video signal must be sufficiently bandlimited to avoid cross-color and crossluminance distortion, and to preclude exceeding the allowable bandwidth of a video channel. The color-difference low-pass filters on the TMC2193 establish chrominance bandwidths which meet the specifications outlined in CCIR Report 624-3, Table II, Item 2.6, for system I over a range of pixel rates from 12.27 Mpps to 14.75 Mpps. Equal bandwidth is established for both colordifference channels.
The TMC2193 has the ability to independently select lines for pedestal insertion during the vertical blanking interval (VBI). For 525-line systems and using the NTSC line numbering convention, in which the first vertical serration is on line 4 for field 1 and line 266 for field 2, the vertical interval lines map to the control registers VBIPEDxy as shown in Table 15.

Enabling the pedestal on line 25 enables it for the remainder of field 1, to line 262. Likewise, enabling the pedestal on line 288 enables it for the remainder of field 2.
Pedestal Height
There are two control registers that set the pedestal height, PEDHGT1, and PEDHGT2. PEDHGT1 determines the height of the pedestal for the luminance channel on the composite path and PDEHGT2 determines the height of the pedestal for the luminance channel on the component path. This allows for independent pedestal control of the composite and component paths. In both cases the range of the pedestal height is from -22.1 to 21.74 IRE in .345 IRE increments.
Sync and Blank Insertion
The TMC2193 includes a flexible closed-caption processor. It may be programmed to insert a closed caption signal on any line within a range of 16 lines on ODD and/or EVEN fields. Closed Caption insertion overrides all other configurations of the encoder: if it is specified on an active video line, it takes precedence over the video data and removes NTSC setup if setup has been programmed for the active video lines. Closed Caption is only available when the TMC2193 is in a 13.5 MHz pixel rate. Closed caption is turned on by setting CCON HIGH. Whenever the encoder begins producing a line specified by CCFLD and CCLINE, it will insert a closed caption line in its place. If CCRTS is HIGH, the data contained in CCDx will be sent. IF CCRTS is LOW, Null bytes (hex 00 with ODD parity) will be sent.
Line Selection
The control register NBMD selects the sync and blank levels for the component path, so that the correct ratio of sync to blank and blank to 100% white for both a 5:2 and 7:3 standards are meet. If NBMD is LOW the component blank level is a D/A code of 256 (314 mV), this is added to the luminance data for YPbPr or all three components for RGB outputs. The component sync level is a D/A code of 12 (14 mV) which is added to the luminance data for YPbPr or to the Green component for RGB outputs. If NBMD is HIGH the component blank level is a D/A code of 240 (295 mV), this is added to the luminance data for YPbPr or all three components for RGB outputs. The component sync level is a D/A code of 8 (9 mV) which is added to the luminance data for YPbPr or to the Green component for RGB outputs. The selection of which components have sync and blank codes added to them is controlled by the OUTMODE control register. Which can select from YPbPr, RGB with sync on green or RGB with external sync. For the composite path the blank and sync D/A codes are determined by the FORMAT control register. For NTSC and PAL-M formats the blank D/A code is 240 (295 mV) and the sync D/A code is 8 (9 mV). For all other PAL formats the blank D/A code is 256 (314 mV) and the sync D/A code is 12 (14 mV). In all cases the sync edges are sloped to insure the proper rise and fall times in all video standards.
The line to contain CC data is selected by a combination of the CCFLD bit and the CCLINE bits. CCLINE is added to the offset shown in Table 16 to specify the line. Table 16. Closed Caption Line Selection Standard 525 625 Offset 12 274 16 328
Parity Generation
Field ODD EVEN ODD EVEN
Lines 12-27 274-289 16-31 328-343
Standard Closed-Caption signals employ ODD parity, which may be automatically generated by setting CCPAR HIGH. Alternatively, parity may be generated externally as part of the bytes to be transmitted, and, with CCPAR LOW, the entire 16 bits loaded into the CCDx registers will be sent unchanged.
Operating Sequence
A typical operational sequence for closed-caption insertion on line xx is: Read Register 1E and check that bit 7 is LOW, indicating that the CCDx registers are ready to accept data. If ready, write two bytes of CC data into registers 1C and 1D. Write into register 1E the proper combination of CCFLD and CCLINE. CCPAR may be written as desired. Set CCRTS HIGH. The CC data is transmitted during the specified line. As soon as CCDx s transferred into the CC processor (and CCRTS goes LOW), new data may be loaded into registers 1C and 1D.

Interpolation Filters
Each video output on the TMC2193 is digitally filtered with sharp-cutoff low-pass interpolation filters. These filters ensure that the frequency band above base-band video and below the pixel frequency (fS/4 to 3fS/4, where fS is the PXCK frequency) are sufficiently suppressed. Since these are fixed-coefficient digital filters, their filter characteristics depend upon clock rate.

PRODUCT SPECIFICATION
Analog outputs of the TMC2193 are driven by four 10 bit D/A converters and separate 9 bit reference D/A converter, operating at twice the pixel rate. The outputs drive standard video levels into 37.5 or 75 Ohm loads. An internal voltage reference is used to provide reference current for the D/A converters. For more accurate levels, an external fixed or variable voltage reference source is accommodated. The video signal levels from the TMC2193 may be adjusted by varying the common Vref or the four independent Rrefs. Each video D/A converter has an independent reference resistor that can adjust the output gain, with the exception of the reference D/A whose reference resistor is shared with DAC1. D/A Matching is achieved by trimming the each external reference resistor of each D/A.

The first three words of ancillary data comprise the TRS signal (ANC2-0) which indicates the end of active video. Also known as the Ancillary data header, the TRS signal is a 00h, FFh, FFh sequence. Except for the TRS words, ancillary data bit 0 (B0, LSB) is odd parity for B7-1. The data type word (TT) is used to specify the ancillary data type. The TMC2193 compares this 7 bit value with the contents of the ANCID control register. If there is a match, the
ancillary data will be processed. If there is no match, the TMC2193 ignores ancillary data. The word count data (D11-0 in MM, LL) in the ancillary data packet indicate the number of words in ancillary data. Ancillary phase data is used to program the MSBs of the PHASE register. ANCPHEN and PHV determine how ancillary phase data is used. When ancillary data is not present, the TMC2193 assumes PHV = LOW.

Note: 1. The F bit is part of the EAV timing reference code and tracks the F0 bit. Operating Modes
The field number bits (F2-0) from the ancillary data packet FIELD word, are used to program the encoder's field counter depending upon the state of the synchronous video flag (SVF) and the ANCTREN bit in the control register. In the basic operating mode (ANCTREN = LOW), all timing is found in the F bit of EAV. F2-0 and SVF are ignored and the encoder subcarrier synthesizer is reset to the PHASE value every eight fields (when the field counter transitions from 111 (field 8) to 000 (field 1). In the basic mode, ANCFREN and ANCPHEN are typically set LOW, ignoring ancillary frequency and phase data. If ANCFREN and ANCPHEN are HIGH, the TMC2193 uses the incoming ancillary frequency and phase data on a lineby-line basis.
REV. 1.0 3/26/03
In genlocking mode (ANCTREN and SVF = HIGH), the subcarrier synthesizer is allowed to free run, with phase and frequency being set from the ancillary data packet PH12-0 and FR31-0 data. The field counter increments just like it does in basic mode. Field sequence mode (ANCTREN = HIGH and SVF = LOW), is the same as basic mode except that the field counter is set by the F2-0 bits in the FIELD word of ancillary data. If ancillary data is not present on a line, the field counter will continue to count as it does in basic mode. When ancillary data is present, the contents of the field counter are loaded with field data (F2-0). In this way, the TMC2193 may be synchronized with an external source by sending field data only once.

The TMC2193 features a robust layering engine with three possible input layers controlled by two keying controls. The layer assignments are shown in Table 22, along with the keying control. The keying controls, KEY pin or OL4-0 are aligned with the incoming pixel data stream and are then delayed throughout the chip to be continuously aligned with the input video streams. A generic overview of the keying and layering features is shown in Figure 21.

Overlay Mixer
The OL[4:0] bus provides the ability to overlay 30 different 24 bit values onto the pixel data path. The 24 bit overlay colors must be the same format as the incoming Pixel data. For Y,Cb,Cr input formats the range of Y values spans the entire range of the format, 1 to 254, this enables super whites and super blacks in the overlay palette. When OL[4:0] is equal to 00h the pixel data port to be the output of the overlay mixer. If OL[4:0] is in the range of 1 to 31 then the output source is one of 30 possible overlay col-
ors, see Table 22. Overlay Address Map. When OL4-0 equal to 16, the overlay mixer produces a pixel data output with half the luminance magnitude and chrominance magnitude. Any OL4-0 value greater than 16 will result in a overlay mix with a full amplitude overlay and the pixel data with half amplitude pixel data (PD) or half amplitude CVBS data as its values. This allows for transparent overlays or produce shadow boxes around overlaid text. The midpoint of the rising and falling edges on the mixed output is determined by the transition of the OL[4:0] pins in

Hardware Keying
The KEY input switches the input to the Comp2 data path between the composite video generated from the PD port and the CVBS data bus on a pixel-by-pixel basis. This is a "soft" switch is executed over 3 PCK periods to minimize out-ofband transients. Keying is accomplished in the digital composite video domain. The coefficients for the mix are 0, 1/8, 1/2, 7/8, and 1 . The COMP2 output is the final output for all overlay functions. The other three D/As will continue to present PD port data when CVBS is active. Hardware keying is enabled by the key Control Register HKEN. Normally, keying is only effective during the active video portion of the encoded video line (as determined by Control Register VA). That is, the horizontal blanking interval is generated by the encoder even if the KEY signal is held HIGH through horizontal blanking. However, it is possible to allow digital horizontal blanking to be passed through from the CVBS bus to the COMP2 output by setting key Control Register BUKEN HIGH. In this mode, KEY is always active, and may be exercised at will. The KEY input is registered into the encoder just as Pixel data is clocked into the PD port. It is internally pipelined, so the midpoint of the KEY transition occurs at the output of the pixel that was input at the same time at the KEY signal.

Parallel Microprocessor Interface
The parallel microprocessor interface is active when SER is HIGH and employs a 12-line interface; an 8 bit data bus and 2 bit address location, 1 bit read/write select, and a chip select controlling the timing. Two addresses are required for device programming, one to the pointer and one to the data location. When writing, the address is presented along with a LOW on the R/W pin during the falling edge of CS. Eight bits of data are presented on D7-0 during the subsequent rising edge of CS.
Data Keying
Data Keying occurs just prior to the gamma block. Data keying for each channel Green/Y, Blue/Cb, and Red/Cr, is separately enabled or disabled by the control registers

In read mode, the address is accompanied by a HIGH on the R/W pin during a falling edge of CS. The data output pins go to a low-impedance state tDOZ after CS falls. Valid data are present on D7-0 tDOM after the falling edge of CS. Because this port operates asynchronously with the pixel timing, there is an uncertainty in this data valid output delay of one PXCK period. This uncertainty does not apply to tDOZ. Writing data to specific control registers of the TMC2193 requires that the 8 bit address of the control register of interest be written prior to the data. This control register address is the base address for subsequent write operations. The base address auto increments by one for each byte of data written after the data byte intended for the base address. If more bytes are transferred than there are available addresses, the address will not increment and remain at its maximum value of 4Ch. Writing data to specific OLUT location of the TMC2193 requires that the 8 bit address of the OLUT location of interest be written prior to the data sequence. This OLUT location address is the base address for subsequent write operations. The base address auto increments by one for each sequence of three (3) bytes of data written after the data byte intended for the base address. The sequence of data transfer is Y or Green, Cb or Blue, Cr or Red, after the Cr or

Serial Control Port (R-Bus)
In addition to the 12-wire parallel port, a 2-wire serial control interface is provided, active when SER is LOW. Either port alone can control the entire chip. Up to four TMC2193 devices may be connected to the 2-wire serial interface with each device having a unique address. The 2-wire interface comprises a clock (SCL) and a bi-directional data (SDA) pin. The encoder acts as a slave for receiving and transmitting data over the serial interface. When the serial interface is not active, the logic levels on SCL and SDA need to be pulled HIGH by external pull-up resistors. Data received or transmitted on the SDA line must be stable for the duration of the positive-going SCL pulse. Data on SDA must change only when SCL is LOW. If SDA changes state while SCL is HIGH, the serial interface interprets that action as a start or stop sequence. There are six components to serial bus operation: * * * * * * Start signal Slave address byte Block Pointer Offset Pointer Data byte to read or write Stop signal
bit indicates the direction of data transfer, read from or write to the slave device. If the transmitted slave address matches the address of the device (set by the state of the SA1-0 input pins in Table 24), the TMC2193 acknowledges by bringing SDA LOW on the 9th SCL pulse. If the addresses do not match, the TMC2193 will not acknowledge. Table 25. Serial Port Addresses A6 1 1 1 1 A5 0 0 0 0 A4 1 1 1 1 A3 0 0 0 0 A2 1 1 1 1 A1 A0 (SA1) (SA0) 0 0 1 1 0 1 0 1
Data Transfer via Serial Interface
For each byte of data read or written, the MSB is the first bit of the sequence. If the TMC2193 does not acknowledge the master device during a write sequence, the SDA remains HIGH so the master can generate a stop signal. If the master device does not acknowledge the TMC2193 during a read sequence, the encoder interprets this as "end of data". Writing data to specific control registers of the TMC2193 requires that the 8 bit address of the control register of interest be written after the slave address has been established. This control register address is the base address for subsequent write operations. The base address auto increments by one for each byte of data written after the data byte intended for the base address.
When the serial interface is inactive (SCL and SDA are HIGH) communications are initiated by sending a start signal. The start signal is a HIGH-to-LOW transition on SDA while SCL is HIGH. This signal alerts all slaved devices that a data transfer sequence is coming. The first eight bits of data transferred after a start signal comprise a seven bit slave address and a single R/W bit.

Data are read from the control registers of the TMC2193 in a similar manner. Reading requires two data transfer operations: The base address must be written with the R/W bit of the slave address byte LOW to set up a sequential read operation.
Reading (the R/W bit of the slave address byte HIGH) begins at the previously established base address. The address of the read register auto increments after each byte is transferred. To terminate a write sequence to the TMC2193, a stop signal must be sent. A stop signal comprises a LOW-to-HIGH transition of SDA while SCL is HIGH. To terminate a read

generating a stop signal to terminate the current communication. This is used to change the mode of communication (read, write) between the slave and master without releasing the serial interface lines.

When LDFID is HIGH, the FLD[2:0] pins are used as inputs to lock the field the that the TMC2193 is encoding. 5 PXCK's after the falling edge of HSIN the FLD[2:0] pins are sampled. When LDFID is LOW, the FLD[2:0] pins output the current field that is being encoded. Soft Key Inversion. When SKFLP is LOW, the key generated by the data keying is a normal state. When SKFLP is HIGH, the key generated by the data keying is a inverted state. DDS Reset. By inserting a logic HIGH into this register the DDS accumulator is reset to SYSPH value at the start of the next field 1 and DDSRST is reset LOW. This enables the DDS to be reset when the encoder is operating with a free running subcarrier. Ancillary Frequency Enable. When HIGH, the encoder gets subcarrier frequency data (FREQ3-0) from incoming ancillary data (in accordance with FRV bit). When LOW, FREQ3-0 registers contain the subcarrier frequency data. Ancillary Phase Enable. When HIGH, the encoder gets subcarrier phase offset data (SCHPHL and SCHPHM) from incoming ancillary data (in accordance with PHV bit). When LOW, a default value of 0000h is used for subcarrier phase. Ancillary Timing Enable. When HIGH, the encoder decodes incoming ancillary data to determine video timing (FIELD and SVF).

This bit is set HIGH by the user when bytes 0x1C and 0x1D have been loaded with the next two bytes to be sent. When the encoder's line count reaches preceding the line specified in bits 4-0 of this register the data will be transferred from registers 0x1C and 0x1D, and RTS will be RESET LOW. A new pair of bytes may then be loaded into registers 0x1C and 0x1D. If CCON = 1 and CCRTS = 0 when the CC line is to be sent, NULL bytes will be sent. Auto Parity Generation. When set HIGH, the encoder replaces the MSB of bytes 0x1C and 0x1D with a calculated ODD parity. When set LOW, the CC processor transmits the 16 bits exactly as loaded into registers 0x1C and 0x1D.

Applications Discussion
The suggested output reconstruction filter is shown in Figure 29. The phase and frequency response for the encoder and the reconstruction filter is shown in Figure 30.

The circuit in Figure 31 shows the connection of power supply voltages, output reconstruction filters and the external voltage reference. All VDD pins should be connected to the same power source. The full-scale output voltage level for each D/A:

D1 DIODE SCHOTTKY A_OUT D2 DIODE SCHOTTKY
VOUTx = IOUTx x RLx = K x IREFx x RLx = K x (VREF/RREFx) x RLx where: * IOUTx is the full-scale output current sourced by the D/A converter. * RLx is the resistive load on the D/A output pin.
C8 100pF
R9 75
L6 1.0H
65-6294-31
* K is a constant for the TMC2193 D/A converters (approximately equal to 34). * IREFx is the reference current flowing out of the RREFx pin to ground. * VREF is the voltage measured on the VREF pin. * RREFx is the total resistance connected between the RREFx pin and ground. The reference voltage in Figure 31 is from an LM185 1.2 Volt band-gap reference. The suggested trim is designed to give 10% of trim around 5K Ohms. This RREFx sets the "gain" for that D/A converter. Varying RREFx 10% will cause the full-scale output voltage on the D/A to vary by 10%. An alternative output reconstruction filter is the SMA-163E, which contains 4 independent reconstruction filter. The phase and frequency response of this filter is shown in the Output Low-Pass Filters Section of this data sheet.

Layout Considerations
Designing with high-performance mixed-signal circuits demands printed circuits with ground planes. Wire-wrap is not an option. Overall system performance is strongly influenced by the board layout. Capacitive coupling from digital to analog circuits may result in poor picture quality. Consider the following suggestions when doing the layout: * Keep analog traces (CBYPx, VREF, RREF, DACx) as short and far from all digital signals as possible. The TMC2193 should be located near the board edge, close to the analog output connectors. The power plane for the TMC2193 should be separate from that which supplies other digital circuitry. A single power plane should be used for all of the VDD pins. If the power supply for the TMC2193 is the same for the system's digital circuitry, power to the TMC2193 should be filtered with ferrite beads and 0.1F capacitors to reduce noise. The ground plane should be solid, not cross-hatched. Connections to the ground plane should be very short.
*
Decoupling capacitors should be applied liberally to pins. For best results, use 0.1F capacitors. Lead lengths should be minimized. Ceramic chip capacitors are the best choice. If there is dedicated digital power plane, it should not overlap the TMC2193 footprint, the voltage reference, or the analog outputs. Capacitive coupling of digital power supply noise from this layer to the TMC2193 and its related analog circuitry can have an adverse effect on performance. The PXCK should be handled carefully. Jitter and noise on this clock or its ground reference will translate to noise on the video outputs. Terminate the clock line carefully to eliminate overshoot and ringing. Connect all unused inputs to the TMC2193 to either ground or VDD. Do not leave them unconnected.

Output Low-Pass Filters
The response at 5.0MHz typically varies < 0.25dB with supplies of 5V to 8V. When operating in the 0dB gain
mode, pin 6 must be well isolated from ground planes. When operating in the +6dB gain mode, pin 6 must have a low resistance path to ground.
