General Description

The LM1204 is a triple 150 MHz video amplifier system designed specifically for high resolution RGB video display applications. In addition to three matched video amplifiers, the LM1204 contains a DC operated contrast control, a DC operated drive control for each amplifier, and a dual clamping system for both brightness control and video blanking. The LM1204 also contains a back porch clamp pulse generator which is activated by an externally supplied ±H/HV sync signal or by an external composite video signal. The ±H/HV sync input will have priority over the composite video input. A single -H/HV sync output is provided for the automatically selected sync input signal. The back porch clamp pulse width is user adjustable from 0.3 µs to 4 µs.

The LM1204 video output stage will directly drive most Hybrid or discrete CRT amplfier input stages without the need for an external buffer transistor. The device has been designed to operate from a 12V supply with all DC controls operating over a 0V to 4V range providing for an easy interface to serial digital buss controlled monitors.
