The LM1290 is a high-performance, low-cost deflection solution for autosync monitors.

n Full autosync.
22 kHz to 110 kHz with no component switching or external adjustments n No manufacturing trims needed.
internal VCO capacitor trimmed on chip n Sample-and-hold circuit for fast top-of-screen phase recovery, even when using composite sync n DC-controlled H phase and duty cycle n Resistor-programmable minimum VCO frequency n Excellent jitter performance n X-ray input disables H drive until VCC powered down n Low VCC disables H drive (VCC < 8.5V) n H output transi.
