Multistandard Video-IF and Quasi Parallel Sound Processing

Description

The TDA4471 is an integrated bipolar circuit for full

multistandard

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), positive modulation

(e.g. L standard) and the AM, FM/NICAM sound IF

signals. Specially two video IF inputs (2 x VIF) in

combination with one sound IF input (1 x SIF) and the

common pinning with the TDA4474 gives flexibility to

design a universal IF module for various applications.

Features

D 5V 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 is operating on picture carrier

frequency, the VCO frequency is switchable for

the L’ mode

D Alignment–free AFC without external reference

circuit, polarity of the AFC curve is switchable

D VIF–AGC for negative modulated signals

(peak sync detection) and for positive modulation

(peak white/black level detector)

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 Complete alignment–free AM demodulator with

gain controlled AF output

D Separate SIF–AGC with average detection

D Parallel operation of the AM demodulator and

QPS mixer (for NICAM–L stereo sound)

D Two video IF inputs (2 x VIFin)

D One sound IF input (1 x SIFin)

D Package and relevant pinning is compatible with

the TDA4474; simplifies the design of an

universal IF module

Package:

30 pin shrink–dual–inline–plastic (SDIP30)
