Multistandard Video-IF + Quasi Parallel Sound Processing
Description
The TDA4470 is an integrated bipolar circuit for multi-
standard 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), positive modulation
(e.g., L standard) and the AM, 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, the
VCO frequency is switchable for L’-mode
D Alignment-free AFC without external reference
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)
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 Complete alignment-free AM demodulator with gain
controlled AF output
D Separate SIF-AGC with average detection
D Two independent SIF inputs
D Parallel operation of the AM demodulator and QPS
mixer (for NICAM-L stereo sound)
D Package and relevant pinning is compatible with the
single standard version TDA4472, which simplifies
the design of an universal IF module
