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
