The control voltage required to tune the VCO from its free-running frequency to actually double the PC frequency is generated by the Frequency-Phase detector and fed via the loop filter to the first variable capacitor (FPLL). This control voltage is amplified and additionally converted into a current which represents the AFC output signal. The VCO centre frequency can be decreased (required for L accent standard) by activating an additional internal capacitor. This is achieved by using the L/L accent gating switch. In this event the second variable capacitor can be controlled by a variable resistor at the L/L accent gating switch for setting the VCO centre frequency to the required L accent value. At centre frequency the AFC output current is equal to zero. FUNCTIONAL DESCRIPTION Vision IF amplifier The vision IF amplifier consists of three AC-coupled differential amplifier stages. Each differential stage comprises a feedback network controlled by emitter degeneration. Tuner and VIF AGC The AGC capacitor voltage is transferred to an internal IF control signal, and is fed to the tuner AGC to generate the tuner AGC output current (pin TAGC, open-collector output). The tuner AGC takeover point can be adjusted. This allows the tuner and the SWIF filter to be matched to achieve the optimum IF input level. The oscillator signal is divided-by-two with a TWD which generates two differential output signals with a 90 degree phase difference independent of the frequency. The AGC detector charges/discharges the AGC capacitor to the required voltage for setting of VIF and tuner gain in order to keep the video signal at a constant level. Therefore for negative video modulation the sync level and for positive video modulation the peak white level of the video signal is detected. In order to reduce the reaction time for positive modulation, where a very large time constant is needed, an additional level detector increases the discharging current of the AGC capacitor (fast mode) in the event of a decreasing VIF amplitude step. The additional level information is given by the black-level detector voltage. Video demodulator and amplifier The video demodulator is realized by a multiplier which is designed for low distortion and large bandwidth. The vision IF input signal is multiplied with the ‘in phase’ signal of the travelling wave divider output. In the demodulator stage the video signal polarity can be switched in accordance with the TV standard. The demodulator output signal is fed via an integrated low-pass filter for attenuation of the carrier harmonics to the video amplifier. The video amplifier is realized by an operational amplifier with internal feedback and high bandwidth. A low-pass filter is integrated to achieve an attenuation of the carrier harmonics for B/G and L standard. The standard dependent level shift in this stage delivers the same sync level for positive and negative modulation. The video output signal is 1 V (p-p) for nominal vision IF modulation. Frequency Phase Locked Loop detector (FPLL) The VIF-amplifier output signal is fed into a frequency detector and into a phase detector via a limiting amplifier. During acquisition the frequency detector produces a DC current proportional to the frequency difference between the input and the VCO signal. After frequency lock-in the phase detector produces a DC current proportional to the phase difference between the VCO and the input signal. The DC current of either frequency detector or phase detector is converted into a DC voltage via the loop filter, which controls the VCO frequency. In the event of positive modulated signals the phase detector is gated by composite sync in order to avoid signal distortion for overmodulated VIF signals. This mode can be switched off by the L/L accent gating switch. Video buffer For an easy adaption of the sound traps an operational amplifier with internal feedback is used in the event of B/G and L standard. This amplifier is featured with a high bandwidth and 7 dB gain. The input impedance is adapted for operating in combination with ceramic sound traps. The output stage delivers a nominal 2 V (p-p) positive video signal. Noise clipping is provided. VCO, Travelling Wave Divider (TWD) and AFC The VCO operates with a resonance circuit (with L and C in parallel) at double the Picture Carrier (PC) frequency. 1999 May 07 TDA9810 6 Philips Semiconductors Product specification Multistandard VIF-PLL with QSS-IF and AM demodulator TDA9810 SIF amplifier and AGC AM demodulator The sound IF amplifier consists of two AC-coupled differential amplifier stages. Each differential stage comprises a controlled feedback network provided by emitter degeneration. The AM demodulator is realized by a multiplier. The modulated SIF amplifier output signal is multiplied in phase with the limited (AM is removed) SIF amplifier output signal. The demodulator output signal is fed via an integrated low-pass filter for attenuation of the carrier harmonics to the AF amplifier. This AM output signal can be muted by using the AM mute switch. The SIF AGC detector is related to the SIF input signals (average level of AM or FM carriers) and controls the SIF amplifier to provide a constant SIF signal to the AM demodulator and single reference QSS mixer. The SIF AGC reaction time is set to ‘slow’ for nominal video conditions. But with a decreasing VIF amplitude step the SIF AGC is set to ‘fast’ mode controlled by the VIF AGC detector. In FM mode this reaction time is also set to ‘fast’ controlled by the standard switch. Internal voltage stabilizer and 1⁄2VP-reference The bandgap circuit internally generates a voltage of approximately 1.25 V, independent of supply voltage and temperature. A voltage regulator circuit, connected to this voltage, produces a constant voltage of 3.6 V which is used as an internal reference voltage. Single reference QSS mixer For all audio output signals the constant reference voltage cannot be used because large output signals are required. Therefore these signals refer to half the supply voltage to achieve a symmetrical headroom, especially for the rail-to-rail output stage. For ripple and noise attenuation the 1⁄2VP voltage has to be filtered via a low-pass filter by using an external capacitor together with an integrated resistor (f−3dB = 5 Hz). For a fast setting to 1⁄2VP an internal start-up circuit is available. The single reference QSS mixer is realized by a multiplier. The SIF amplifier output signal is fed to the single reference QSS mixer and converted to intercarrier frequency by the regenerated picture carrier (VCO). The mixer output signal is fed via a high-pass for attenuation of the video signal components to the output pin 10. With this system a high performance hi-fi stereo sound processing can be achieved. 1999 May 07 7 Philips Semiconductors Product specification Multistandard VIF-PLL with QSS-IF and AM demodulator TDA9810 LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 134).

Values of video and sound parameters are decreased at VP = 4.5 V. 2. This parameter is not tested during production and is only given as application information for designing the television receiver. 3. Loop bandwidth BL = 70 kHz (natural frequency fn = 12 kHz; damping factor d ≈ 3; calculated for peak level). Resonance circuit of VCO: Q0 > 50; Cext = 8.2 pF ±0.25 pF; Cint ≈ 8.5 pF (loop voltage ≈2.7 V). 4. Temperature coefficient of external LC-circuit is equal to zero. 5. Vi(IF)(rms) = 10 mV; ∆f = 1 MHz (VCO frequency offset related to picture carrier frequency); white picture video modulation. 6. Vi(IF) signal for nominal video signal. 7. Offset current measured between pin 4 and half of supply voltage (VP = 2.5 V) under the following conditions: no input signal at VIF input (pins 1 and 2) and VIF amplifier gain at minimum (V21 = VP). Due to sample-and-hold mode of the FPLL in L standard, the leakage current of the loop filter capacitor (C = 220 nF) should not exceed 500 nA. 8. Measurements taken with SAW filter K6257 (sound carrier suppression: 40 dB); loop bandwidth = 70 kHz. a) Modulation VSB; sound carrier off; fvideo > 0.5 MHz. b) Sound carrier on; SIF SAW filter K9453; fvideo = 10 kHz to 10 MHz. 9. The 7 dB buffer gain accounts for 1 dB loss in the sound trap. Buffer output signal is typically 2 V (p-p), in event of CVBS video amplifier output typical 1 V (p-p). If no sound trap is applied a 330 Ω resistor must be connected from output to input (from pin 9 to pin 13). 10. The leakage current of the AGC capacitor should not exceed 1 µA at B/G standard respectively 10 nA current at L standard. Larger currents will increase the tilt. 11. S/N is the ratio of black-to-white amplitude to the black level noise voltage (RMS value, pin 12). B = 5 MHz weighted in accordance with “CCIR 567”. 12. The intermodulation figures are defined: V 0 at 4.4 MHz α IM ( 1.1 ) = 20 log ------------------------------------- + 3.6dB ; αIM(1.1) value at 1.1 MHz referenced to black/white signal; V 0 at 1.1 MHz V 0 at 4.4 MHz α IM ( 3.3 ) = 20 log -------------------------------------- ; αIM(3.3) value at 3.3 MHz referenced to colour carrier. V 0 at 3.3 MHz 13. Response speed valid for a VIF input level range of 200 µV up 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 Fig.8. The AFC-steepness can be changed by the resistors at pin 17. 1999 May 07 16 Philips Semiconductors Product specification Multistandard VIF-PLL with QSS-IF and AM demodulator TDA9810 15.

For picture to sound carrier ratio see Table 1. The NICAM L subcarrier is 17 dB lower than the AM sound carrier and depends on its AM modulation. 18. The Vo QSS output (pin 10) is analysed by a test demodulator TDA9820. The S/N ratio of this IC is more than 60 dB, related to a deviation of ±27 kHz, in accordance with “CCIR 468-4”. 19. For all S/N measurements the used vision IF 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 (deviation ±27 kHz) for 6 kHz sine wave black-to-white video modulation. c) Picture-to-sound carrier ratio; PC/SC1 = 13 dB; (transmitter). 20. Measurements taken with SAW filter K6257 (Siemens) for vision IF (suppressed sound carrier) and K9453 (Siemens) for sound IF (suppressed picture carrier). Input level Vi(SIF)(rms) = 10 mV, 27 kHz (54% FM deviation). 21. The PC/SC ratio at pins 1 and 2 is calculated as the addition of TV transmitter PC/SC ratio and SAW filter PC/SC ratio. This PC/SC ratio is necessary to achieve the S/NW values as noted. A different PC/SC ratio will change these values. 22. Measurements taken with SAW filter K9453 (Siemens) for AM sound IF (suppressed picture carrier). 23. The input voltage has to be Vi > 2.8 V, or open-circuit.

The top-surface temperature of the packages should preferable be kept below 230 °C. SOLDERING Introduction 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). 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. There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mount components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mount ICs, or for printed-circuit boards with high population densities. In these situations reflow soldering is often used. 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. Through-hole mount packages SOLDERING BY DIPPING OR BY SOLDER WAVE • For packages with leads on two sides and a pitch (e): The maximum permissible temperature of the solder is 260 °C; solder at this temperature must not be in contact with the joints for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds. – 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 device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg(max)). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. 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. MANUAL SOLDERING Apply the soldering iron (24 V or less) to the lead(s) of the package, either below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 °C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 °C, contact may be up to 5 seconds. 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 is 4 seconds at 250 °C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. Surface mount packages REFLOW SOLDERING MANUAL 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. 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. Several methods exist for reflowing; for example, infrared/convection heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. 1999 May 07 When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 °C. 27 Philips Semiconductors Product specification Multistandard VIF-PLL with QSS-IF and AM demodulator TDA9810 Suitability of IC packages for wave, reflow and dipping soldering methods SOLDERING METHOD MOUNTING PACKAGE WAVE REFLOW(1) DIPPING Through-hole mount DBS, DIP, HDIP, SDIP, SIL suitable(2) − suitable Surface mount not suitable suitable − suitable − suitable − not recommended(4)(5) suitable − not recommended(6) suitable − BGA, SQFP suitable(3) HLQFP, HSQFP, HSOP, HTSSOP, SMS not PLCC(4), SO, SOJ suitable LQFP, QFP, TQFP SSOP, TSSOP, VSO Notes 1. 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”. 2. For SDIP packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board. 3. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink (at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version). 4. 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. 5. Wave soldering is only suitable for LQFP, QFP and TQFP packages with a pitch (e) equal to or larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 6. Wave soldering is only suitable for SSOP and TSSOP 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.
