Values of video and sound parameters can be decreased at VP = 4.5 V. The time constant (R x C) at the supply must be > 1.2 s (e.g. 1 and 2.2 F). Condition: luminance range (5 steps) from 0 % to 100 %. AC load: CL < 20 pF and RL > 1 k. The sound carrier frequencies (depending on the TV standard) are attenuated by the integrated sound carrier traps (see Figure 12 to Figure 17; H(s) is the absolute value of the transfer function). S/NW(video) is the ratio of the black-to-white amplitude to the black level noise voltage (RMS value measured on pin CVBS). B = 5 MHz (B/G, I and D/K standard). Noise analyzer setting: 200 kHz high-pass and SC-trap switched on. Conditions: video signal, grey level and negative modulation. Pin REF is able to operate as a 1-pin crystal oscillator input as well as an external reference signal input, e.g. from the tuning system.

8. Functional description
A simplified block diagram of the device is illustrated in Figure 1. The device contains the following functional blocks: 1. VIF amplifier 2. Tuner AGC and VIF AGC 3. VIF AGC detector 4. Frequency Phase-Locked Loop (FPLL) detector 5. VCO and divider 6. AFC and digital acquisition help circuit 7. Video demodulator and amplifier 8. Sound carrier trap 9. SIF amplifier 10.SIF AGC detector 11.Single reference QSS mixer 12.AM demodulator 13.FM demodulator and acquisition help circuit 14.Audio amplifier and mute time constant 15.Internal voltage stabilizer 16.Logic.
8.1 VIF amplifier
The VIF amplifier consists of three AC-coupled differential stages. Gain control is performed by emitter degeneration. The total gain control range is typical 66 dB. The differential input impedance is typical 2 k in parallel with 3 pF.
8.2 Tuner AGC and VIF AGC
This block adapts the voltage, generated at the VIF AGC detector, to the internal signal processing at the VIF amplifier and performs the tuner AGC control current generation. The onset of the tuner AGC control current generation can be set by a potentiometer at pin TOP.
8.3 VIF AGC detector
Gain control is performed using sync level detection (negative modulation) or peak white detection (positive modulation). For negative modulation, the sync level voltage is stored in an integrated capacitor by means of a fast peak detector. This voltage is compared with a reference voltage (nominal sync level) by a comparator which charges or discharges the integrated AGC capacitor to generate the VIF gain. The time constants for decreasing or increasing the gain are nearly equal and the total AGC reaction time is fast, to cope with `aeroplane fluttering'.

TDA9882
Multistandard vision and QSS FM sound IF PLL demodulator
For positive modulation, the white peak level voltage is compared with a reference voltage (nominal white level) by a comparator which charges (fast) or discharges (slow) the external AGC capacitor directly for the generation of the required VIF gain. The need of a very large time constant for VIF gain increase is caused by the fact that the peak white level may appear only once in a field. In order to reduce this time constant, an additional level detector increases the discharging current of the AGC capacitor (fast mode) in the event of a decreasing VIF amplitude step controlled by the detected actual black level voltage. The threshold level for fast mode AGC is typical -6 dB video amplitude. The fast mode state is also transferred to the SIF AGC detector for speed-up. In case of missing peak white pulses, the VIF gain increase is limited to typical 3 dB by comparing the detected actual black level voltage with a corresponding reference voltage.
8.4 FPLL detector
The VIF amplifier output signal is fed to a frequency detector and a phase detector via a limiting amplifier to remove the video AM. During acquisition the frequency detector produces a current that is proportional to the frequency difference between the VIF and the VCO signal. After frequency lock-in the phase detector produces a current that is proportional to the phase difference between the VIF and the VCO signal. The currents from the frequency and phase detector are charged into the loop filter which controls the VIF VCO and locks it to the frequency and phase of the VIF carrier. For a positive modulated VIF signal, the charging currents are gated by the composite sync in order to avoid signal distortion in case of overmodulation. The gating depth is set to 0 %.
8.5 VCO and divider
The VCO of the VIF FPLL operates as an integrated low radiation relaxation oscillator at twice the picture carrier frequency. The control voltage, required to tune the VCO to actually double the picture carrier frequency, is generated at the loop filter by the frequency phase detector. The possible frequency range is 50 MHz to 140 MHz (typical value). The oscillator frequency is divided-by-two to provide two differential square wave signals with exactly 90 degrees phase difference, independent of the frequency, for use in the FPLL detectors, the video demodulator and the single reference QSS mixer.
8.6 AFC and digital acquisition help circuit
Each relaxation oscillator of the VIF PLL and FM PLL demodulator has a wide frequency range. To prevent false locking of the PLLs, with respect to the catching range, the digital acquisition help circuit provides an individual control until the frequency of the VCO is within the preselected standard dependent lock-in window of the PLL. The VIF carrier frequencies 38.9 MHz (M/N, B/G, I, D/K and L standard), 45.75 MHz (NTSC standard) and 33.9 MHz (L-accent standard) can be selected via pin VIF0 and pin QSSO with resistor; see Table 4. The FM carrier frequencies can be selected via pin FM0 and pin FM1; see Table 5.

Multistandard vision and QSS FM sound IF PLL demodulator
The in-window and out-window control at the FM PLL can additionally be used to mute the audio stage (if auto mute is selected via pins SIF1 and SIF2); see Table 6. The principle working of the digital acquisition help circuit is as follows: The PLL VCO output is connected to a downcounter which has a predefined start value (standard dependent). The VCO frequency clocks the downcounter for a fixed gate time. Thereafter, the downcounter stop value is analyzed. In the event that the stop value is higher (lower) than the expected value range, the VCO frequency will be lower (higher) than the required lock-in window frequency range. A positive (negative) control current is injected into the PLL loop filter which causes the VCO frequency to be increased (decreased) and a new counting cycle starts. The gate time as well as the control logic of the acquisition help circuit is dependent on the precision of the reference signal at pin REF. Operation as a crystal oscillator is possible as well as connecting this input via a serial capacitor to an external reference frequency e.g. the tuning system oscillator. The AFC signal is derived from the corresponding downcounter stop value after a counting cycle. The last four bits are latched and the digital-to-analog converted value is given as current at pin AFC.
8.7 Video demodulator and amplifier
The video demodulator is realized by a multiplier which is designed for low distortion and large bandwidth. The VIF signal is multiplied with the `in phase' signal of the VIF PLL VCO. The demodulator output signal is fed into the video preamplifier via a level shift stage with integrated low-pass filter to achieve carrier harmonics attenuation. The output signal of the preamplifier is fed to the VIF AGC detector (see Section 8.3) and also fed internally to the integrated sound carrier trap; see Section 8.8. The differential trap output signal is converted and amplified by the following postamplifier. The video output level at pin CVBS is 2 V (p-p). Noise clipping is provided.
8.8 Sound carrier trap
The sound carrier trap consists of a reference filter, a phase detector and the sound trap itself. A sound carrier reference signal is fed into the reference low-pass filter and is shifted by nominal 90 degrees. The phase detector compares the original reference signal with the signal shifted by the reference filter and produces a DC voltage by charging or discharging an integrated capacitor with a current proportional to the phase difference between both signals, respectively to the frequency error of the integrated filters. The DC voltage controls the frequency position of the reference filter and the sound trap. Thus the accurate frequency position for the different standards is set by the sound carrier reference signal. The sound trap itself is constructed of three separate traps to realize sufficient suppression of the first and second sound carrier.

8.9 SIF amplifier
The SIF amplifier consists of three AC-coupled differential stages. Gain control is performed by emitter degeneration. The total gain control range is typical 66 dB. The differential input impedance is typical 2 k in parallel with 3 pF.
8.10 SIF AGC detector
SIF gain control is performed by the detection of the DC component of the AM demodulator output signal. This DC signal is directly corresponding to the SIF voltage at the output of the SIF amplifier so that a constant SIF signal is supplied to the AM demodulator and to the single reference QSS mixer. By switching the gain of the input amplifier of the SIF AGC detector dependent on modulation select, the internal SIF level for FM sound is 5.5 dB lower than for AM sound. This is done to adapt the SIF AGC characteristic to the VIF AGC characteristic. The adaption is ideal for a picture-to-sound FM carrier ratio of 13 dB. Via a comparator the integrated AGC capacitor is charged or discharged for the generation of the required SIF gain. Due to AM sound, the AGC reaction time is slow (fc < 20 Hz for the closed AGC loop). For reducing this AM sound time constant in the event of a decreasing IF amplitude step, the load current of the AGC capacitor is increased (fast mode) when the VIF AGC detector (at positive modulation mode) operates in the fast mode too. An additional circuit (threshold approximately 7 dB) ensures a very fast gain reduction for a large increasing IF amplitude step.
8.11 Single reference QSS mixer
With the present system high performance Hi-Fi stereo sound processing can be achieved. The single reference QSS mixer generates the 2nd FM TV sound intercarrier signal. It is realized by a linear multiplier which multiplies the SIF amplifier output signal and the VIF PLL VCO signal which is locked to the picture carrier. The QSS mixer output signal is fed internally via a high-pass and low-pass combination to the FM demodulator as well as via an operational amplifier to the QSS output pin QSSO.
8.12 AM demodulator
The amplitude modulated SIF amplifier output signal is fed both to a two-stage limiting amplifier for removing the AM and to a linear multiplier. The result of the multiplication of the SIF signal with the limiter output signal is AM demodulation (passive synchronous demodulator). The demodulator output signal is fed via a low-pass filter for the attenuation of carrier harmonics and via the input amplifier of the SIF AGC detector to the audio amplifier.
8.13 FM demodulator and acquisition help circuit
The narrow-band FM PLL detector consists of:
* Gain controlled FM amplifier and AGC detector * Narrow-band PLL.

TDA9882
Multistandard vision and QSS FM sound IF PLL demodulator
The intercarrier signal from the single reference QSS mixer is fed to the input of an AC-coupled gain controlled amplifier with two stages. The gain controlled output signal is fed to the phase detector of the narrow-band FM PLL (FM demodulator). For good selectivity and robustness against disturbance caused by the video signal, a high linearity of the gain controlled FM amplifier and of the phase detector as well as a constant signal level are required. The gain control is done by means of an `in phase' demodulator for the FM carrier (from the output of the FM amplifier). The demodulation output is fed into a comparator for charging or discharging the integrated AGC capacitor. This leads to a mean value AGC loop to control the gain of the FM amplifier. The FM demodulator is realized as a narrow-band PLL with an external loop filter, which provides the necessary selectivity (bandwidth approximately 100 kHz). To achieve good selectivity, a linear phase detector and a constant input level are required. The gain controlled intercarrier signal from the FM amplifier is fed to the phase detector. The phase detector controls, via the loop filter, the integrated low radiation relaxation oscillator. The designed frequency range is from 4 MHz to 7 MHz. The VCO within the FM PLL is phase-locked to the incoming 2nd SIF signal which is frequency modulated. The VCO control voltage is superimposed by the AF voltage. Therefore, the VCO tracks with the FM of the 2nd SIF signal. Thus, the AF voltage is present at the loop filter and is typically 5 mV (RMS) for 27 kHz FM deviation. This AF signal is fed via a buffer to the audio amplifier. The correct locking of the PLL is supported by the digital acquisition help circuit; see Section 8.6.
8.14 Audio amplifier and mute time constant
The audio amplifier consists of two parts:
* AF preamplifier * AF output amplifier.
The AF preamplifier used for FM sound is an operational amplifier with internal feedback, high gain and high common mode rejection. The AF voltage from the PLL demodulator is 5 mV (RMS) for a frequency deviation of 27 kHz and is amplified by 30 dB. By using a DC operating point control circuit (with external capacitor CAF), the AF preamplifier is decoupled from the PLL DC voltage. The low-pass characteristic of the amplifier reduces the harmonics of the sound intercarrier signal at the AF output terminal. For FM sound a switchable de-emphasis network (with external capacitor) is implemented between the preamplifier and the output amplifier. The de-emphasis time constant with 50 s or 75 s depends on the FM carrier selection via pins FM0 and FM1; see Table 5. The AF output amplifier provides the required AF output level by a rail-to-rail output stage. A preceding stage makes use of an input selector for switching between the FM sound, AM sound and mute state. Switching to the mute state is controlled automatically, depending on the digital acquisition help circuit should the VCO of the FM PLL not be in the required frequency window. This is done by a time constant: fast for switching to the mute state and slow (typically 40 ms) for switching to the non-mute state. Auto mute can be disabled via pins SIF1 and SIF2 with resistor; see Table 6.

8.15 Internal voltage stabilizer
The band gap circuit internally generates a voltage of approximately 2.4 V, independent of the supply voltage and the temperature. A voltage regulator circuit, connected to this voltage, produces a constant voltage of 3.55 V which is used as an internal reference voltage.
8.16 Logic
The logic circuit detects the logic level at the logic ports VIF0, FM0 and FM1 as well as the presence of resistors (DC current to ground) at pins QSSO, SIF1 and SIF2 and controls the internal functions; see Table 4 to Table 6. In the event that all logic ports are open-circuit (high-ohmic or CMOS HIGH level) TV standard NTSC with a vision carrier frequency of 45.75 MHz, an FM sound carrier frequency of 4.5 MHz, de-emphasis with 75 s time constant and auto mute on is selected.

Loop bandwidth BL = 70 kHz (damping factor d = 1.9; calculated with sync level within gain control range). Calculation of the VIF PLL filter can be done by use of the following formula:
1 BL - 3dB = ----- O K D R , valid for d 1.2 -K 2 1 d = -- R K O K D C , 2
where:
Hz A rad KO is the VCO steepness ------ or 2 ------ ; KD is the phase detector steepness ------ ; V V rad
R is the loop resistor; C is the loop capacitor; BL-3dB is the loop bandwidth for -3 dB; d is the damping factor. [5] [6] [7] [8] Vi(VIF) = 10 mV (RMS); f = 1 MHz (VCO frequency offset related to picture carrier frequency); white picture video modulation. Condition: luminance range (5 steps) from 0 % to 100 %. S/NW(video) is the ratio of black-to-white amplitude to the black level noise voltage (RMS value measured on pin CVBS). B = 5 MHz (B/G, I and D/K standard). Noise analyzer setting: 200 kHz high-pass and SC-trap switched on. The intermodulation figures are defined for: a) f = 1.1 MHz (referenced to black and white signal) as IM = 20 log ---------------------------------- + 3.6 dB V at 1.1 MHz
0
V 0 at 4.4 MHz
b) f = 3.3 MHz (referenced to color carrier) as IM = 20 log ---------------------------------- V at 3.3 MHz

V 0 at 4.4 MHz
[9]
Modulation Vestigial Side-Band (VSB); sound carrier off; fvideo > 0.5 MHz. Measurements taken with SAW filter M1963M (sound shelf: 20 dB); loop bandwidth BL = 70 kHz.
[10] Sound carrier on; fvideo = 10 kHz to 10 MHz. Measurements taken with SAW filter M1963M (sound shelf: 20 dB); loop bandwidth BL = 70 kHz. [11] Conditions: video signal, grey level and negative modulation. [12] AC load; CL < 20 pF and RL > 1 k. The sound carrier frequencies (depending on TV standard) are attenuated by the integrated sound carrier traps (see Figure 12 to Figure 17; H(s) is the absolute value of transfer function). [13] The response time is valid for a VIF input level range from 200 V to 70 mV. [14] To match the AFC output signal to different tuning systems a current source output is provided. The test circuit is given in Figure 9. The AFC slope (voltage per frequency) can be changed by resistors R1 and R2. [15] The tolerance of the reference frequency determines the accuracy of the VIF AFC, FM demodulator center frequency and maximum FM deviation. [16] For negative modulation no DC load at pin QSSO is allowed. Positive modulation mode will be activated by the application of a 2.2 k resistor between pin QSSO and ground. [17] SIF input level is 10 mV (RMS); VIF input level is 10 mV (RMS) unmodulated. [18] Measured with an FM deviation of 25 kHz and the typical AF output voltage of 500 mV (RMS). For handling a frequency deviation of more than 55 kHz, the AF output signal has to be reduced in order to avoid clipping (THD < 1.5 %) by means of a resistor Rx with external application at pin AFD (see Figure 22 and Figure 23). [19] The lower limit of the audio bandwidth depends on the value of the capacitor at pin AFD. A value of CAF = 470 nF leads to fAF(-3dB) 20 Hz and CAF = 220 nF leads to fAF(-3dB) 40 Hz. [20] For all S/N measurements the used VIF modulator has to meet the following specifications: a) Incidental phase modulation for black-to-white jump less than 0.5 degrees. b) QSS AF performance, measured with the television demodulator AMF2 (audio output, weighted S/N ratio) better than 60 dB (at deviation 27 kHz) for 6 kHz sine wave black-to-white video modulation. c) Picture-to-sound carrier ratio PC/SC1 = 13 dB (transmitter).

[21] Calculation of the loop filter can be done approximately by use of the following formulae:
1 K OK D f o = ----- --------------CP 2 1 = ---------------------------------2R K O K D C P BL - 3dB = f o ( 1.55 - )
The formulae are only valid under the following conditions: 1 and CS > 5CP

capacitor; CP is the parallel capacitor; fo is the natural frequency of PLL; BL-3dB is the loop bandwidth for -3 dB; is the damping factor. For examples, see Table 10. [22] The PC/SC ratio is calculated as the addition of TV transmitter PC/SC1 ratio and SAW filter PC/SC1 ratio. This PC/SC ratio is necessary to achieve the S/NW values as noted. A different PC/SC ratio will change these values. [23] The QSS signal output on pin QSSO is analyzed by a test demodulator TDA9820. The S/N ratio of this device is more than 60 dB, related to a deviation of 27 kHz, in accordance with "CCIR 468". [24] Measurements taken with SAW filter G3962 for vision IF (suppressed sound carrier) and K9350 for sound IF (suppressed picture carrier). Input level Vi(SIF) = 10 mV (RMS), 27 kHz (54 % FM deviation). [25] Measurements taken with SAW filter K9453 (Siemens) for AM sound IF (suppressed picture carrier). [26] The value of Cx determines the accuracy of the resonance frequency of the crystal. It depends on the used type of crystal. [27] Pin REF is able to operate as a 1-pin crystal oscillator input as well as an external reference signal input, e.g. from the tuning system.

15. Soldering
15.1 Introduction to soldering surface mount packages
This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our Data Handbook IC26; Integrated Circuit Packages (document order number 9398 652 90011). There is no soldering method that is ideal for all surface mount IC packages. Wave soldering can still be used for certain surface mount ICs, but it is not suitable for fine pitch SMDs. In these situations reflow soldering is recommended.
15.2 Reflow soldering
Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Driven by legislation and environmental forces the worldwide use of lead-free solder pastes is increasing. Several methods exist for reflowing; for example, convection or convection/infrared heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 seconds and 200 seconds depending on heating method. Typical reflow peak temperatures range from 215 C to 270 C depending on solder paste material. The top-surface temperature of the packages should preferably be kept:
* below 225 C (SnPb process) or below 245 C (Pb-free process)
- for all BGA, HTSSON..T and SSOP..T packages - for packages with a thickness 2.5 mm - for packages with a thickness < 2.5 mm and a volume 350 mm3 so called thick/large packages.
* below 240 C (SnPb process) or below 260 C (Pb-free process) for packages with a
thickness < 2.5 mm and a volume < 350 mm3 so called small/thin packages. Moisture sensitivity precautions, as indicated on packing, must be respected at all times.
15.3 Wave soldering
Conventional single wave soldering is not recommended for surface mount devices (SMDs) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. To overcome these problems the double-wave soldering method was specifically developed. If wave soldering is used the following conditions must be observed for optimal results:
* Use a double-wave soldering method comprising a turbulent wave with high upward
pressure followed by a smooth laminar wave.
* For packages with leads on two sides and a pitch (e):
- larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board;

- smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves at the downstream end.
* For packages with leads on four sides, the footprint must be placed at a 45 angle to
the transport direction of the printed-circuit board. The footprint must incorporate solder thieves downstream and at the side corners. During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Typical dwell time of the leads in the wave ranges from 3 seconds to 4 seconds at 250 C or 265 C, depending on solder material applied, SnPb or Pb-free respectively. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications.
15.4 Manual soldering
Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 C. When using a dedicated tool, all other leads can be soldered in one operation within 2 seconds to 5 seconds between 270 C and 320 C.

For more detailed information on the BGA packages refer to the (LF)BGA Application Note (AN01026); order a copy from your Philips Semiconductors sales office. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the Drypack information in the Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods. These transparent plastic packages are extremely sensitive to reflow soldering conditions and must on no account be processed through more than one soldering cycle or subjected to infrared reflow soldering with peak temperature exceeding 217 C 10 C measured in the atmosphere of the reflow oven. The package body peak temperature must be kept as low as possible.

These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side, the solder might be deposited on the heatsink surface. If wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. The package footprint must incorporate solder thieves downstream and at the side corners. Wave soldering is suitable for LQFP, QFP and TQFP packages with a pitch (e) larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. Wave soldering is suitable for SSOP, TSSOP, VSO and VSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. Image sensor packages in principle should not be soldered. They are mounted in sockets or delivered pre-mounted on flex foil. However, the image sensor package can be mounted by the client on a flex foil by using a hot bar soldering process. The appropriate soldering profile can be provided on request. Hot bar soldering or manual soldering is suitable for PMFP packages.
