Datasheet Summary
Multistandard Video-IF and Quasi Parallel Sound Processing
Description
The TDA4470 is an integrated bipolar circuit for multistandard 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 Intercarrier output signal is gain controlled (necessary for digital sound processing)
D plete alignment-free AM demodulator with...
