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 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 is operating on picture carrier frequency
Alignment-free AFC without external reference
circuit
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
Gain controlled intercarrier output signal
(supports digital sound processing systems)
Separate SIF-AGC with average detection
Two independent SIF inputs
Package and pinning is fully compatible with the
multistandard version TDA4470, simplifies the
design of an universal IF module
Package
28 pin shrink-dual-inline-plastic (SDIP28)
