TDA9565H Overview
The various versions of the TDA955X/6X/8X H/N1 series bine 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.
TDA9565H Key Features
- 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 additi
- 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 vision IF and mono intercarrier sound circuit can be used for the demodulation of FM radio signals
- Video switch with 2 external CVBS inputs and a CVBS output. One of the CVBS inputs can be used as Y/C input
- 2 external audio inputs. The selection of the various inputs is coupled to the selection of the CVBS signals
- Integrated chrominance trap circuit
- Integrated luminance delay line with adjustable delay time
