The LM1253A pre-amp is an integrated high voltage triple CRT pre-amp and Analog On
Screen Display (OSD) generator. The IC is I2C controlled, and allows control of all the
parameters necessary to setup and adjust the brightness and contrast in the CRT display. In
addition, it provides a programmable period vertical blanking pulse which is used to blank
the G1.
The LM1253A pre-amp is designed to work in cooperation with the LM2453 driver, and
