Additional preview pages of the LM1290 datasheet.

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

The LM1290 provides full autosync capability, DC controls and complete freedom from manufacturing trims.

Its continuous capture range is from 22 kHz to 110 kHz (1:5).

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.
