Description: Multistandard Video-IF and Quasi Parallel Sound Processing

Features

* D 5V supply voltage; low power consumption D Active carrier generation by FPLL principle D Alignment
* free quasi parallel sound (QPS) mixer for FM/NICAM sound IF signals D Intercarrier output signal is gain controlled (frequency
* phase
* locked
* loop) synchronous demodul

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. Four IF inputs (2 x VIF plus 2 x SIF) and the common pinning with TDA4471 gives flexibility to design a universal IF module for va
