Video-IF and Quasi Parallel Sound Processing
Description
The TDA4472 is an integrated bipolar circuit for 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), and the FM/NICAM sound IF signals.
Features
5 V supply voltage; low power consumption
Active carrier generation by FPLL principle
(frequency-phase-locked-loop) for true
synchronous demodulation
Very linear video demodulation, good pulse response
and excellent intermodulation figures
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
Alignment-free quasi parallel sound (QPS) mixer for
FM/NICAM sound IF signals
Intercarrier output signal is gain controlled (necessary
for digital sound processing)
Separate SIF-AGC with average detection
Two independent SIF inputs
Package and relevant pinning is compatible with the
multistandard version TDA4470, which simplifies the
design of an universal IF module
