SDA5231-5

The SDA5231-5 is designed to separate teletext signals from TV signals for a microcontroller-operated I2C bus concept. Its function is the processing of the teletext informations, the system clock generation and the switching of HV synchronization signals.

Features of the SDA5231-5 are:(1)crystal-stable data clock regeneration for a bit rate of 6.9375MHz;(2)separation and regeneration of teletext information;(3)separation of the horizontal and vertical synchronization signals;(4)phase-locked coupling of 6MHz oscillator with comp.video;(5)optional adjustment to 1V or 2.5V comp.video level;(6)processing of externally separated teletext data;(7)output of negative and positive synchronous signals to television set.

The absolute maximum ratings of the SDA5231-5 can be summarized as:(1)supply voltage:13.2V;(2)storage temperature range:-40 to 125;(3)output current VSC:5mA;(4)output current TTD:10mA;(5)output TTC:10mA;(6)output current F6:10mA;(7)output current sync.:5mA;(8)thermal resistance system-air:50K/W;(9)ambient temperature in operation:0 to 70.
