Datasheet Summary
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,...
