TDA4472-M - Video-IF and Quasi Parallel Sound Processing

General 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.

Key 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, good pulse response and excellent intermodulation figures D VCO circuit operates at picture carrier frequency D Alignment-free AFC without.
