The IC is I2 C compatible, and 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. 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 the additional black level clamp capacitors. The IC is packaged in an industry standard 24-lead DIP molded plastic package. FEATURES 110 MHz bandwidth preamplifier with full video signal parametric control. I 2 C compatible interface to micro-controller. 4 external 8-bit DACs for bus controlled Bias and brightness. On Screen Display(OSD) mixing. Auto Beam current limiting. Suitable for use with discrete or integrated clamp, with software configurable brightness mixer. Power Save (Green) Mode, 80% power reduct...
