TDA4472-M

Video-IF and Quasi Parallel Sound Processing

Description

The TDA4472 is an integrated bipolar circuit for video/

sound IF (VIF/SIF) signal processing in TV/VCR and

multimedia applications. The circuit processes all TV

video IF signals with negative modulation (e.g., B/G

standard), and the FM/NICAM sound IF signals.

Features

D 5 V supply voltage; low power consumption

D Active carrier generation by FPLL principle

(frequency-phase-locked-loop) for true

synchronous demodulation

D Very linear video demodulation, good pulse response

and excellent intermodulation figures

D VCO circuit operates at picture carrier frequency

D Alignment-free AFC without external reference

circuit, polarity of the AFC curve is switchable

D VIF-AGC with peak sync. detection

D Tuner AGC with adjustable take over point

D Alignment-free quasi parallel sound (QPS) mixer for

FM/NICAM sound IF signals

D Intercarrier output signal is gain controlled (necessary

for digital sound processing)

D Separate SIF-AGC with average detection

D Two independent SIF inputs

D Package and relevant pinning is compatible with the

multistandard version TDA4470, which simplifies the

design of an universal IF module
