TDA 6930
Wireless Components
Specification, August 1999
2.1 Overview
The TDA 6930 is an integrated circuit for high class multistandard TV vision IF
signal, sound IF signal and AM-Audio signal processing.
FM and NICAM sound IF carriers are converted to their intercarrier frequency.
All switching functions are controlled via open collector transistors.
Outputs for threshold controlled tuner AGC , digital tuning AFC , DF and AM-AF
for all terrestrial standards are available.
2.2 Features
s
FPLL carrier regeneration from sound channel without nyquist slope for best
sound S/N and pulse response
s
Choice of 2 VIF / SIF switchable inputs
