General 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.

Overview

TDA4470-M Multistandard Video-IF and Quasi Parallel Sound Processing.

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 Intercarrier output signal is gain controlled (necessary for digital sound processing) D Complete alignment-free AM demodulator with gain controlled AF output D Very linear video demodulation, good pulse response and excellent intermodulation figures D Separate SIF-AGC with average detection D Two independent SIF inputs D Parallel operati.
