TDA4472-M

Video-IF and Quasi Parallel Sound Processing

Description

The TDA4472 is an integrated bipolar circuit for video/ video IF signals with negative modulation (e.g., B/G

sound IF (VIF/SIF) signal processing in TV/VCR and standard), and the FM/NICAM sound IF signals.

multimedia applications. The circuit processes all TV

Features

5 V supply voltage; low power consumption

Alignment-free quasi parallel sound (QPS) mixer for

FM/NICAM sound IF signals

Active carrier generation by FPLL principle

(frequency-phase-locked-loop) for true

synchronous demodulation

Intercarrier output signal is gain controlled (necessary

for digital sound processing)

Separate SIF-AGC with average detection

Two independent SIF inputs

Very linear video demodulation, good pulse response

and excellent intermodulation figures

Package and relevant pinning is compatible with the

multistandard version TDA4470, which simplifies the

design of an universal IF module

VCO circuit operates at picture carrier frequency

Alignment-free AFC without external reference

circuit, polarity of the AFC curve is switchable

VIF-AGC with peak sync. detection

Tuner AGC with adjustable take over point

Package: SDIP28, SO28
