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.

The raster height and the raster vertical position can be controlled by two DC voltage input pins that adjust the sawtooth waveform amplitude and the variable DC output voltage. The East-West correction of the LM1296 has height tracking and vertical position tracking capabilities. As the height or position of the raster is adjusted the geometry correction is maintained by the chip automatically.

The LM1296 is packaged in a 16-pin plastic DIP package.
