4-3 TDA 4470-Multistandard Video-IF and Quasi Parallel Sound Processor

4-3-1- Description

The TDA 4470 is an integrated bipolar circuit for multi-standard 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.

4-3-2-Features

-5V supply voltage ; low power consumption.

-Active carrier generation by FPLL principle (frequency-phase-locked-loop) for true synchronous demodulation.

-Very linear video demodulation, good pulse response and excellent intermodulation figures.

-Alignment-free AFC without external reference circuit, polarity of the AFC curve is switchable.

-VIF-AGC for negative modulated signals (peak sync. detection) and for positive modulation

(peak white/black level detector).

-Tuner AGC with adjustable take over point.

-Alignment-free quasi parallel sound (QPS) mixer for FM/NICAM sound IF signals.

-Intercarrier output signal is gain controlled (necessary for digital sound processing).

-Complete alignment-free AM demodulator with gain controlled AF output.

-Separate SIF-AGC with average detection

-Two independent SIF inputs

-Parallel operation of the AM demodulator and QPS mixer (for NICAM-L stereo sound).
