Multistandard Video-IF and Quasi Parallel Sound Processing

Description

The TDA4474 is an integrated bipolar circuit for full Four IF inputs (2 x VIF plus 2 x SIF) and the common

multistandard video/sound IF (VIF/SIF) signal pinning with TDA4471 gives flexibility to design a

processing in TV/VCR and Multimedia applications. The universal IF module for various applications.

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.

Features

D 5V supply voltage; low power consumption

D Alignment–free quasi parallel sound (QPS) mixer

for FM/NICAM sound IF signals

D Active carrier generation by FPLL principle

(frequency–phase–locked–loop)

synchronous demodulation

for

true D Intercarrier output signal is gain controlled

(necessary for digital sound processing)

D Very linear video demodulation, good pulse D Complete alignment–free AM demodulator with

response and excellent intermodulation figures gain controlled AF output

D VCO circuit is operating on picture carrier D Separate SIF–AGC with average detection

frequency, the VCO frequency is switchable for

D Parallel operation of the AM demodulator and

the L’ mode

QPS mixer (for NICAM–L stereo sound)

D Alignment–free AFC without external reference

D Four IF inputs (2 x VIFin and 2 x SIFin)

circuit, polarity of the AFC curve is switchable

D Package and relevant pinning is compatible with

D VIF–AGC for negative modulated signals

the TDA4471; simplifies the design of an

(peak sync detection) and for positive modulation

universal IF module

(peak white/black level detector)

Package:

D Tuner AGC with adjustable take over point

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