WT9102

The WT9102 pre-amp is an integrated CMOS CRT preamp and On Screen Display (OSD) generator. It has an I²C interface which allows control of all the parameters necessary to directly setup and adjust the gain and contrast in the CRT display. Brightness and bias can be controlled through the DAC outputs which are well matched to the integrated bias clamp ICs. The WT9102 pre-amp is also designed to be compatible with the high gain driver family.

Black level clamping of the signal is carried out directly on the AC coupled input signal into the high impedance preamplifier input, thus eliminating the need for additional black level clamp capacitors. Horizontal and vertical blanking of the outputs is provided and the length of the vertical blanking is register programmable. The WT9102 is packaged in an industry standard 24 lead DIP molded plastic package.
