TDA9564PS Overview
The various versions of the TDA955X/6X/8X PS/N1 series bine the functions of a video processor together with a µ-Controller and US Closed Caption decoder. Several versions have a Teletext decoder on board. The Teletext decoder has an internal RAM memory for 1or 10 page text.
TDA9564PS Key Features
- Multi-standard vision IF circuit with alignment-free PLL demodulator
- Internal (switchable) time-constant for the IF-AGC circuit
- A choice can be made between versions with mono intercarrier sound FM demodulator and versions with QSS IF amplifier. In
- The mono intercarrier sound circuit has a selective FM-PLL demodulator which can be switched to the different FM sound f
- The FM-PLL demodulator can be set to centre frequencies of 4.74/5.74 MHz so that a second sound channel can be demodulat
- The QSS amplifier and mono intercarrier sound circuit of some versions can be used for the demodulation of FM radio sign
- Source selection between the ‘internal’ CVBS and one external CVBS or Y/C signal
- Integrated chrominance trap circuit
- Integrated luminance delay line with adjustable delay time
- Picture improvement features with peaking (with switchable centre frequency, depeaking, variable positive/negative overs
