GENERAL DESCRIPTION
TDA2579BFEATURES
● Horizontal phase detector, (sync to oscillator), sync separator and noise inverter● Triple current source in the phase detector with automatic selection
● Second phase detector for storage compensation of the horizontal output
● Stabilized direct starting of the horizontal oscillator and output stage from mains supply
● Horizontal output pulse with constant duty cycle value of 29 µs
● Internal vertical sync separator, and two integration selection times
● Divider system with three different reset enable windows
● Synchronization is set to 628 divider ratio when no vertical sync pulses and no video transmitter is identified
● Vertical comparator with a low DC feedback signal
● 50/60 Hz identification output combined with mute function
● Automatic amplitude adjustment for 50 and 60 Hz and blanking pulse duration
● Automatic adaption of the burst-key pulsewidth PACKAGE OUTLINE 18-lead dual in line; plastic (SOT 102); SOT102-1; 1996 November 19. Sep...
