TDA4470-D

Multistandard Video-IF and Quasi Parallel Sound Processing

Description

The TDA4470 is an integrated bipolar circuit for multi- modulation (e.g., B/G standard), positive modulation

standard video/sound IF (VIF/SIF) signal processing in (e.g., L standard) and the AM, FM/NICAM sound IF

TV/VCR and multimedia applications. The circuit signals.

processes all TV video IF signals with negative

Features

5 V supply voltage; low power consumption

Intercarrier output signal is gain controlled (necessary

for digital sound processing)

Active carrier generation by FPLL principle

(frequency-phase-locked-loop) for true

synchronous demodulation

Complete alignment-free AM demodulator with gain

controlled AF output

Very linear video demodulation, good pulse response

and excellent intermodulation figures

Separate SIF-AGC with average detection

Two independent SIF inputs

VCO circuit operates at picture carrier frequency, the

VCO frequency is switchable for L’-mode

Parallel operation of the AM demodulator and QPS

mixer (for NICAM-L stereo sound)

Alignment-free AFC without external reference

circuit, polarity of the AFC curve is switchable

Package and relevant pinning is compatible with the

single standard version TDA4472, which simplifies

the design of an universal IF module

VIF-AGC for negative modulated signals (peak sync.

detection) and for positive modulation (peak white/

black level detector)

Tuner AGC with adjustable take over point

Alignment-free quasi parallel sound (QPS) mixer for

FM/NICAM sound IF signals
