LM1292 Video PLL System for Continuous-Sync Monitors April 1999 LM1292 Video PLL System for Continuous-Sync Monitors General Description The LM1292 is a very low jitter, integrated horizontal time base solution specifically designed to operate in high performance, 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 syn...
