230 Mhz Video Amplifier System - National Semiconductor

The LM2202 is a very high frequency Video Amplifier system intended for use in high resolution monochrome or RGB color monitor applications. In addition to the wideband Video Amplifier the LM2202 contains a gated differential input black level clamp Comparator for brightness control, a DC con- trolled Attenuator for contrast control and a DC controlled sub contrast Attenuator for drive control. The DC control for the contrast Attenuator is pinned out separately to provide a more accurate control system for RGB color monitor applica- tions. All DC controls offer a high input impedance and oper- ate over a 0V to 4V range for easy Interface to bus controlled alignment systems. The LM2202 operates from a nominal 12V supply but CAN be operated with supply voltages down to 8V for applications that require reduced IC package power dissipation characteristics.
