INTEGRATED CIRCUITS DEVICE DATASPECIFICATION SHEET www.DataSheet4U.com TDA955X/6X/8X H/N1 series TV signal processor-Teletext decoder with embedded µ-Controller Tentative Device Speciﬁcation File under Integrated Circuits, Version: 1.6 2000 Jun 22 Previous version: 2000 Apr 06 Philips Semiconductors Tentative Device Speciﬁcation TV signal processor-Teletext decoder with embedded µ-Controller 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 receivers with 90° and 110° picture tubes. www.DataSheet4U.com 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 (4.5/5.5/6.0/6.5 MHz).
