Product specification
Multistandard/MAC VIF-PLL with QSS-IF
and dual FM-PLL/AM demodulator
TDA9815
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.
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/SC
1
= 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 V
i 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 V
i
> 2.8 V or open-circuit.
