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 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 Very linear video demodulation, goo...
