WT9103

The WT9103 pre-amp is an integrated CMOS CRT preamp and On Screen Display (OSD) generator. It has an I²C  nterface which allows control of all the parameters necessary to directly setup and adjust the gain and contrast in  he CRT display. Brightness and bias can be controlled through the DAC outputs.

Black level clamping of the signal is carried out directly on the AC coupled input signal into the high impedance  reamplifier input, thus eliminating the need for additional black level clamp capacitors. Horizontal and vertical  lanking of the outputs is provided and the length of the vertical blanking is register programmable. The WT9103 is  ackaged in an industry standard 24 lead DIP molded plastic package.
