Clock input (CKI: Pin 63) The master clock input (CKI: Pin 63) of this IC supports TTL level input. In addition, two modes can be set: a mode in which the CKI is used as is for the internal master clock (SLCK (Pin 64): L) and a mode in which CKI is halved using the internal frequency divider (SLCK: H). In the latter mode, all internal operation is at 1/2 clock, so "clock" in the description below refers to this 1/2 clock when SLCK is H. Internal operation is at a frequency up to 41 MHz, so when inputting a clock faster than this to CKI1, be sure to set SLCK to H.

HSYNC, VST, HST Input a standard horizontal sync signal to the input HSYNC (Pin 60). At this time, the input polarity is not fixed and is set by the serial data setting HSYNCPOL. In addition, make sure the VST and HST pulses satisfy the following phase relationship. However, when not using pulse eliminator display, HST (Pin 4) can be fixed to H level. Normally input the VST pulse to the LCD panel for the VST input.

Description of Output Correction Signal Operation Horizontal direction The correction data set in the SRAM by serial transfer is arithmetically processed inside the IC to determine the output position corresponding to the value set by serial register HP7 to 0 using the front edge of HSYNC as the reference. Interpolation is not performed for the horizontal direction, and interpolated data is output at the cycle set by serial register HINT7 to 0 for the vertical direction. In addition, the maximum amplitude of the correction signal output voltage is determined by VRH (Pin 44) and VRL (Pin 40). The internal DAC outputs at the resistive potential division (VRH to VRL: 213 typ.), so be sure to input to VRH and VRL via buffers having current capacity.
HSYNC DACKO/I Set by HP7 to 0 Set by HINT7 to 0
DOUT VRH DACO VRL
The internally generated digital data DOUT is input to the internal D/A converter, latched by the D/A converter clock input from DACKI, and output from DACO2, 1 and 0 as an analog signal. Note) If edges remain, these level differences may appear as vertical stripes. Therefore, when using this as a correction signal, be sure to eliminate the edges using an LPF, etc. before input to the CXA2111R or CXA2112R.

Serial Transfer Operation Control method The operation timing of this IC is controlled by serial data. The control data is divided into 8-bit units. The first 8 bits are the main address, the next 8 bits are the sub address, and the subsequent data is 8-bit data blocks. The main address specifies which of the blocks in the table below are to be set. Data is set in the blocks indicated by "1", so if the main address is set to "0F", the subsequent data is set in all data blocks. In addition, the value set in the sub address sets the initial write address in the block specified by the main address. Thereafter, the write address is incremented by +1 while SCTR is L for each 8 bits of data from the address set by the sub address. This makes it possible to set only the necessary data from an optional address. The data set by serial register INIT5 to 0 is output in place of the correction data during serial transfer.

The SRAM numbers 0, 1 and 2 correspond to the DAC output DACO numbers 0, 1 and 2. The correction point data set in the SRAM is reflected to the outputs of the corresponding numbers. Correction point data 0, 1 and 2 Correction point data is set in the 6-bit x 208 words (16 horizontal points, 13 vertical points) SRAM. The set correction data undergoes vertical interpolation and other arithmetic processing, and is then reflected to the DACO0, 1 and 2 outputs, respectively. The correction point data is 6 bits, and is set in D5, 4, 3, 2, 1 and 0. Setting to D7 and 6 is invalid. See the figure on page 13 for the relationship between the correction point data position and the SRAM address. Example) When the main address is set to 04 and the sub address is set to 08, data is written from address 08 of correction point data 2 (SRAM2), then the address is automatically incremented and written to the SRAM. - 12 -

HP7 to 0 This sets the correction signal output start position in the horizontal direction. The timing until the start of correction signal output is set using the front edge of HSYNC as the reference. However, do not set HP7 to 0 to a value of 54 or less, as the arithmetically processed correction signal may not be output correctly in this case. In addition, the waveform may be disturbed by the HP and HINT values and the VST phase. In these cases, eliminate the disturbance by adjusting the HP and DACKO phase.

DACO
HINT7 to 0 This sets the correction point interval in the horizontal direction. Normally, when using 16 points in the horizontal direction, calculate the number of clocks at which the horizontal period can be divided into 16 sections taking into account the input clock and the system clock speed, and then set this value - 1. However, do not input a value of 11 or less to HINT7 to 0, as the internal arithmetic processing may not be able to keep up and the correct value may not be output in this case. Example 1) Inputting a dot clock 40MHz signal to a SVGA panel (800 x 600) If 1/2 the dot clock is input as the master clock and the mode without internal 1/2 frequency division (SLCK: L) is used: HINT = (800 / 16 / 2) - 1 = 24 Example 2) Inputting a dot clock 65MHz signal to a XGA panel (1024 x 768) If 1/2 the dot clock is input as the master clock and the mode with internal 1/2 frequency division (SLCK: H) is used: HINT = (1024 / 16 / 4) - 1 = 15

VP3 to 0 This sets the correction signal output start position in the vertical direction. The number of line counted from the front edge of the VST pulse at which vertical arithmetic processing of the correction signal starts is set. The correction data for the initial line is output continuously only for the number of lines set by VP. VINT4 to 0 This sets the arithmetic processing interval for vertical correction. Vertical correction arithmetic processing is performed every number of lines set by VINT. Normally set arithmetic processing for each line (VINT = 1). ANM5 to 0 This sets the correction point interval in the vertical direction. There are 13 vertical correction points with respect to the actual panel display area switching, so this sets the number of lines at which correction points are spaced for the internal arithmetic processing. Example) To use the full correction point data in the vertical direction, set the correction point interval ANM as follows. SVGA panels: ANM = 600 / 12 = 50 (110010) XGA panels: ANM = 76 / 12 = 64 (000000) 1/A6 to 0 This sets the inverse of ANM. Set the 6th to 12th digits below the decimal point in binary format with 7 bits. Linear interpolation with an accuracy of 1 bit is performed using this setting value. Example) ANM = 50: 1/50 (decimal) = 0.000001010010 (binary) Set the 6th to 12th digits. Example) ANM = 64: 1/64 (decimal) = 0.000001000000 (binary) Set the 6th to 12th digits.

HSOFF This is the correction ON/OFF setting. When H, correction is on; when L, correction is off and the INIT5 to 0 data is output constantly. Normally set HSOFF to H. HPOL This sets the HSYNC input signal polarity. Set HPOL to H for positive polarity, and to L for negative polarity. Be sure to set the polarity correctly in accordance with the input signal. VSPOL This sets the VST input signal polarity. Set VSPOL to H for positive polarity, and to L for negative polarity. Be sure to set the polarity correctly in accordance with the input signal. The Sony timing generator ICs CXD2464R and CXD3500R output an inverse polarity VST pulse for up/down inverse drive of a SVGA panel. Therefore, take special care for the VST polarity when using this IC with a SVGA panel. DWN, RGT DWN and RGT set up/down and right/left inversion, respectively. Normal scan is supported when DWN is H and RGT is H, and up/down and/or right/left inversion of the panel is supported by reading the correction data set in the RAM in the reverse order when these are set to L, respectively. These settings can be controlled from the external pins of the same name DWN (Pin 5) and RGT (Pin 6) by setting CTRL (Pin 7) to H. In this case these serial settings are invalid. DACKP2 to 0 This sets the DAC clock phase. Normally set to "2" to satisfy the internal DAC clock and data setup/hold specifications. STBY1 and 0 This is the standby setting. Standby mode results when STBY1, 0 are set to H, L. At this time, the internal clock is supplied only to the serial interface block, and operation of all other blocks is stopped. Buffer outputs AOUT2, 1 and 0 and digital outputs DOUT25 to 20, 15 to 10 and 05 to 00 are all high impedance at this time. INIT5 to 0 This sets the DACO output level when correction is off. When serial data HSOFF is set to L, the data for this setting is output regardless of the correction data set in the RAM.
