TDA4471 Datasheet (TEMIC Semiconductors) - Multistandard Video-IF and Quasi Parallel Sound Processing

TDA4471, Multistandard Video-IF and Quasi Parallel Sound Processing

The TDA4471 is an integrated bipolar circuit for full 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
