TV signal processor-Teletext decoder with embedded µ-Controller
Tentative Device Specification
TDA955X/6X/8X H/N1 series
GENERAL 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 www.DataShereet4cUei.vcoemrs with 90° and 110° picture tubes.
The ICs have supply voltages of 8 V and 3.3 V and they are mounted in a QFP 80 envelope.
The features are given in the following feature list. The differences between the various ICs are given in the table on page 4.
FEATURES
TV-signal processor
Multi-standard vision IF circuit with alignment-free PLL demodulator
Internal (switchable) time-constant for the IF-AGC circuit
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
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/...
