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.
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.
TMPA8895PSCNGXXX is the latest development of Toshiba G88 Series Combo TV special decoder chip( can be used in 14 “to 29” in ).
The movement, and has a variety of extensions, enabling the full range from simple to high-end movement on a single PCB board. Under the surface is Characteristics TMPA8895PSCNGXXX and possess Introduction.
