LM1296 - Raster Geometry Correction System

General Description

The LM1296 is a monolithic IC for use in the raster scanning circuitry of a multi-frequency CRT monitor.

The IC provides an S-corrected sawtooth waveform and a variable DC output voltage.

These two outputs drive the vertical deflection amplifier.

LM1296 Raster Geometry Correction System for Multi-Frequency Displays February 1998 LM1296 Raster Geometry Correction System for Multi-Frequency Displays General Description The LM1296 is a monolithic IC for use in the raster scanning circuitry of a multi-frequency CRT monitor. The IC provides an S-corrected sawtooth waveform and a variable DC output voltage. These two outputs drive the vertical deflection amplifier. It also provides another waveform for East-West geometry correction which includes pincushion, corner, and trapezoid controls. The geometry correction is controlled by DC input voltages from 0V to 4V.
