LM2202

LM2202 230 MHz Video Amplifier System April 1999 LM2202 230 MHz Video Amplifier System General Description 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 controlled 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 applications. All DC controls offer a high input impedance and operate 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. n tr, tf = 1.5 ns at VO = 4 VPP n Externally gated comparator for brightness control n 0V to 4V high input impedance DC contrast control ( > 40 dB range) n 0V to 4V high input impedance DC drive control ( ± 3 dB range) n Easy to parallel three LM2202s for optimum color tracking in RGB systems n Output stage clamps to 0.65V and provides up to 9V output voltage swing n Output stage directly drives most hybrid or discrete CRT amplifier stages n Replacement for the LM1202 Applications n n n n High resolution CRT monitors Video sw...
