LM1292 Datasheet Video Pll System

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM1292 Video PLL System for Continuous-Sync Monitors April 1999 LM1292 Video PLL System for Continuous-Sync.

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 posite video sync stripper.

Key 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.
