Multistandard Video-IF and Quasi Parallel Sound Processing

Description

The TDA4471 is an integrated bipolar circuit for full (e.g. L standard) and the AM, FM/NICAM sound IF

multistandard video/sound IF (VIF/SIF) signal signals. Specially two video IF inputs (2 x VIF) in

processing in TV/VCR and Multimedia applications. The combination with one sound IF input (1 x SIF) and the

circuit processes all TV video IF signals with negative common pinning with the TDA4474 gives flexibility to

modulation (e.g. B/G standard), positive modulation design a universal IF module for various applications.

Features

D 5V supply voltage; low power consumption

D Intercarrier output signal is gain controlled

(necessary for digital sound processing)

D Active carrier generation by FPLL principle

(frequency–phase–locked–loop)

synchronous demodulation

for

true D Complete alignment–free AM demodulator with

gain controlled AF output

D Very linear video demodulation, good pulse D Separate SIF–AGC with average detection

response and excellent intermodulation figures

D Parallel operation of the AM demodulator and

D VCO circuit is operating on picture carrier

frequency, the VCO frequency is switchable for

the L’ mode

QPS mixer (for NICAM–L stereo sound)

D Two video IF inputs (2 x VIFin)

D One sound IF input (1 x SIFin)

D Alignment–free AFC without external reference

D Package and relevant pinning is compatible with

the TDA4474; simplifies the design of an

universal IF module

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)

Package:

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

D Tuner AGC with adjustable take over point

D Alignment–free quasi parallel sound (QPS) mixer

for FM/NICAM sound IF signals
