Product Summary
The SDA5200S is a data silcer for teletext, designed to separate teletext signals from TV signals for a microcontroller-operated I2C bus concept. The video processor meets the requirements for teletext data clock regeneration and synchronization of the TV set during teletext operation. At the same time, the video signals (CVBS) provided by the television set are evaluated for the teletaxt decoder.
Parametrics
SDA5200S absolute maximum ratings: (1)Supply voltage, V16/13: 13.2V; (2)Storage temperature range, Tstg: -40 to 125℃; (3)Output current VCS, -I25H: 5mA; (4)Output current TTD, -I15H: 10mA; (5)Output current TTC, -I14H: 10mA; (6)Output current F6, -I17H: 10mA; (7)Output current sync, I1: 10mA; (8)Thermal resistance system-sir, RthSA: 50K/W.
Features
SDA5200S features: (1)Crystal-stable data clock regeneration for a bit rate of 6,9375 MHz; (2)Separation and regeneration of teletext information ; (3)Separation of the horizontal and vertical synchronization signals; (4)Phase-locked couping of 6-MHz oscollator with comp. video; (5)Optional adjustment to 1V or 2.5V comp. video level; (6)Processing of externally separated data; (7)Output of negative and positive synchronous sighnals to television set.
