National Semiconductor LM1267 150 MHz I 2 C Compatible RGB Video Amplifier System with OSD DACs handbook
Datasheet
LM1267 is an integrated CMOS CRT pre-amplifier with I2C compatible interface and comprehensive video signal parameter control. It can directly set up and adjust the gain and contrast of the CRT display. The LM1267 pre-amplifier works in cooperation with the LM246X high gain driver family, allowing control of brightness and bias through DAC outputs, and is well matched with the LM2479 and LM2480 integrated bias clamp IC.
