Description
The LM1292 is a very low jitter, integrated horizontal time base solution specifically designed to operate in high performance, continuous-sync video monitors.
Features
- n Wide continuous autosync range.
- 22 kHz.
- 125 kHz (1:5.7) with no component switching or external adjustments n No manufacturing trims required.
- internal VCO capacitor trimmed on chip n No costly high-precision components needed n Very low phase jitter (below 800 ps at 125 kHz) n DC controlled H phase and duty cycle n Video mute pulse for blanking during H frequency transitions n Input sync prioritization n Clamp pulse position and width control n Continuous clamp pulse.
