TDA9552H-N3-3-1623 datasheet

 

Description :

The various versions of the TDA955X/6X/8X H/N1 series combine the functions of a video processor together with a µ-Controller and US Closed Caption decoder. Most
versions have a Teletext decoder on board. The Teletext decoder has an internal RAM memory for 1or 10 page text. The ICs are intended to be used in economy television
receivers with 90° and 110° picture tubes.

Pinout

TDA9552H pinout

 

Features

1. TV-signal processor
(1) Multi-standard vision IF circuit with alignment-free PLL demodulator
(2) Internal (switchable) time-constant for the IF-AGC circuit
(3) The QSS and mono FM functionality are both available so that an FM/AM TV receiver can be built without the use of additional ICs
(4) The mono intercarrier sound circuit has a selective FM-PLL demodulator which can be switched to the different FM sound frequencies (4.5/5.5/6.0/6.5 MHz). The quality of this system is such that the external band-pass filters can be omitted.
