TDA4472-M
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
D 5 V 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 operates at picture carrier frequency
D Alignment-free AFC without external reference
circuit, polarity of the AFC curve is switchable
D VIF-AGC with peak sync. detection
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 Separate SIF-AGC with average detection
D Two independent SIF inputs
D Package and relevant pinning is compatible with the
multistandard version TDA4470, which simplifies the
design of an universal IF module
