LM1204V

150 MHz RGB Video Amplifier System

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 clamp-

ing system for both brightness control and video blanking.

The LM1204 also contains a back porch clamp pulse gener-

ator which is activated by an externally supplied gH/HV

sync signal or by an external composite video signal. The

gH/HV sync input will have priority over the composite vid-

eo input. A single bH/HV sync output is provided for the

automatically selected sync input signal. The back porch

clamp pulse width is user adjustable from 0.3 ms to 4 ms.

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 inter-

face to serial digital buss controlled monitors.
