Multistandard/MAC VIF-PLL with QSS-IF and dual FM-PLL/AM demodulator
FUNCTIONAL DESCRIPTION The integrated circuit comprises the functional blocks as shown in Fig.1: * Vision IF amplifier and input switch * Tuner and VIF-AGC * Frequency Phase Locked Loop detector (FPLL) * VCO, Travelling Wave Divider (TWD) and AFC * Video demodulator and amplifier * Video buffer * SIF amplifier and AGC * Single reference QSS mixer * AM demodulator * FM-PLL demodulator * Internal voltage stabilizer and 12VP-reference. Vision IF amplifier and input switch The vision IF amplifier consists of three AC-coupled differential amplifier stages. Each differential stage comprises a feedback network controlled by emitter degeneration. The first differential stage is extended by two pairs of emitter followers to provide two IF input channels. The VIF input can be selected by pin 30. 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 (open-collector output). The tuner AGC takeover point can be adjusted. This allows the tuner and the SAW filter to be matched to achieve the optimum IF input level. 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 (or MAC) 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.
TDA9815
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. VCO, Travelling Wave Divider (TWD) and AFC The VCO operates with a resonance circuit (with L and C in parallel) at double the PC frequency. The VCO is controlled by two integrated variable capacitors. 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 (FPLL) and fed via the loop filter to the first variable capacitor. 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 accent switch. In this event the second variable capacitor can be controlled by a variable resistor at the L accent switch for setting the VCO centre frequency to the required L accent value. At centre frequency the AFC output current is equal to zero. 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. 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.

Multistandard/MAC VIF-PLL with QSS-IF and dual FM-PLL/AM demodulator
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. 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. For MAC standard a second buffer amplifier with 6 dB gain is used. This buffer amplifier is selected by the standard switch. SIF amplifier and AGC 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 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. Single reference QSS mixer 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 20. With this system a high performance hi-fi stereo sound processing can be achieved. AM demodulator
TDA9815
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. FM-PLL demodulator Each FM-PLL demodulator consists of a limiter, an FM-PLL and an AF amplifier. The limiter provides the amplification and limitation of the FM sound intercarrier signal before demodulation. The result is high sensitivity and AM suppression. The amplifier consists of 7 stages which are internally AC-coupled in order to minimize the DC offset and to save pins for DC decoupling. At the input of one limiter a signal switch is available for selecting one of the two intercarrier signals. Controlled by the voltage at pin 11, either the input pin 17 or pin 18 is active for handling different intercarrier frequencies. The other limiter is extended with an additional level detector consisting of a rectifier and a comparator. By means of this the AF2 signal is set to mute and the PLL VCO is switched off, if the intercarrier signal at pin 16 is below 1 mV (RMS) in order to avoid false identification of a stereo decoder. Note that noise at pin 16 disables the mute state (at low SIF input signal), but this will not lead to false identification. This `auto-mute' function can be disabled by connecting a 5.6 k resistor from pin 16 to VP (see Fig.13). Furthermore the AF output signals can be muted by connecting a resistor between the limiter inputs pin 16 or pin 17 and ground. The FM-PLL consists of an integrated relaxation oscillator, an integrated loop filter and a phase detector. The oscillator is locked to the FM intercarrier signal, output from the limiter. As a result of locking, the oscillator frequency tracks with the modulation of the input signal and the oscillator control voltage is superimposed by the AF voltage. The FM-PLL operates as an FM-demodulator.

Multistandard/MAC VIF-PLL with QSS-IF and dual FM-PLL/AM demodulator
The AF amplifier consists of two parts: 1. The AF preamplifier for FM sound is an operational amplifier with internal feedback, high gain and high common mode rejection. The AF voltage from the PLL demodulator, by principle a small output signal, is amplified by approximately 33 dB. The low-pass characteristic of the amplifier reduces the harmonics of the intercarrier signal at the sound output terminal. An additional DC control circuit is implemented to keep the DC level constant, independent of process spread. 2. The AF output amplifier (10 dB) provides the required output level by a rail-to-rail output stage. This amplifier makes use of an input selector for switching to AM/FM or mute state, controlled by the standard switching voltage and the mute switching voltage. Internal voltage stabilizer and 12VP-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.

TDA9815
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 12VP voltage has to be filtered via a low-pass filter by using an external capacitor together with an integrated resistor (fg = 5 Hz). For a fast setting to 12VP an internal start-up circuit is added.

4. Loop bandwidth BL = 75 kHz (natural frequency fn = 11 kHz; damping factor d 3.5; calculated with sync level within gain control range). Resonance circuit of VCO: Q0 > 50; Cext = 8.2 pF 0.25 pF; Cint 8.5 pF (loop voltage approximately 2.7 V). 5. Temperature coefficient of external LC-circuit is equal to zero. 6. Vi IF = 10 mV RMS; f = 1 MHz (VCO frequency offset related to picture carrier frequency); white picture video modulation. 7. Vi IF signal for nominal video signal. 8. Measurements taken with SAW filter G3962 (sound carrier suppression: 40 dB); loop bandwidth BL = 75 kHz: a) Modulation VSB; sound carrier off; fvideo > 0.5 MHz. b) Sound carrier on; SIF SAW filter L9453; fvideo = 10 kHz to 10 MHz. 9. The 7 dB buffer gain accounts for 1 dB loss (not valid for MAC) in the sound trap. Buffer output signal is typical 2 V (p-p), in event of CVBS video amplifier output typical 1 V (p-p). If no sound trap is applied a 330 resistor must be connected from output to input (from pin 21 to pin 22). 10. The leakage current of the AGC capacitor should not exceed 1 A 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 10). B = 5 MHz weighted in accordance with "CCIR 567". 12. The intermodulation figures are defined: V 0 at 4.4 MHz 1.1 = 20 log ------------------------------------- + 3.6dB; 1.1 value at 1.1 MHz referenced to black/white signal; V 0 at 1.1 MHz V 0 at 4.4 MHz 3.3 = 20 log ------------------------------------- ; 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 V 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.7. The AFC-steepness can be changed by the resistors at pin 23. 15. Depending on the ratio C/C0 of the LC resonant circuit of VCO (Q0 > 50; see note 4; C0 = Cint + Cext). 16. Input level for second IF from an external generator with 50 source impedance. AC-coupled with 10 nF capacitor, fmod = 1 kHz, 27 kHz (54% FM deviation) of audio references. A VIF/SIF input signal is not permitted. Pins 8 and 28 have to be connected to positive supply voltage for minimum IF gain. S/N and THD measurements are taken at 50 s de-emphasis. The not tested FM-PLL has to be locked to an unmodulated carrier. a) Second IF input level 10 mV RMS. 17. Measured with an FM deviation of 27 kHz the typical AF output signal is 500 mV RMS (Rx = Ry = 0 ; see Fig.13). By using Rx = Ry = 470 the AF output signal is attenuated by 6 dB (250 mV RMS) and adapted to the stereo decoder family TDA9840. For handling an FM deviation of more than 53 kHz the AF output signal has to be reduced by using Rx and Ry in order to avoid clipping (THD < 1.5%). For an FM deviation up to 100 kHz an attenuation of 6 dB is recommended with Rx = Ry = 470 . 18. The leakage current of the decoupling capacitor (2.2 F) should not exceed 1 A. 19. In the event of activated auto mute state the second FM-PLL oscillator is switched off, if the input signal at pin 16 is missing or too weak (see Fig.13). In the event of switching the second FM-PLL oscillator on by the auto mute stage an increased DC jump is the consequence. Note, that noise at pin 16 disables the mute state (at low SIF input signal), but this will not lead to false identification of the used stereo decoder family TDA9840.

20. 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.
TDA9815
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). 21. Measurements taken with SAW filter G3962 (Siemens) for vision IF (suppressed sound carrier) and G9350 (Siemens) for sound IF (suppressed picture carrier). Input level Vi SIF = 10 mV RMS, 27 kHz (54% FM deviation). 22. 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/N(W) values as noted. A different PC/SC ratio will change these values. 23. Measurements taken with SAW filter L9453 (Siemens) for AM sound IF (suppressed picture carrier). 24. The input voltage has to be Vi > 2.8 V or open-circuit.

SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "IC Package Databook" (order code 9398 652 90011). Soldering by dipping or by wave The maximum permissible temperature of the solder is 260 C; solder at this temperature must not be in contact with the joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds. DEFINITIONS Data sheet status Objective specification Preliminary specification Product specification Limiting values
TDA9815
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. Repairing soldered joints Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, 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.
This data sheet contains target or goal specifications for product development. This data sheet contains preliminary data; supplementary data may be published later. This data sheet contains final product specifications.
Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability. Application information Where application information is given, it is advisory and does not form part of the specification. LIFE SUPPORT APPLICATIONS These products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be expected to result in personal injury. Philips customers using or selling these products for use in such applications do so at their own risk and agree to fully indemnify Philips for any damages resulting from such improper use or sale.
