LM1291 Video PLL System for Continuous-Sync Monitors
General Description
The LM1291 is an integrated horizontal time base solution specifically designed to operate in continuous-sync video monitors It automatically synchronizes to any H frequency from 22 kHz to 125 kHz and provides the drive pulse to the high power deflection circuit Available sync processing includes a vertical sync separator and a composite video sync stripper An internal sync selection scheme gives highest priority to separate H and V sync then composite sync and finally sync on video no external switching between sync sources is necessary The LM1291 provide...
