Monolithic IC MM1207, 1205
Outline
MM1207XD and MM1205XD are wideband RGB video amplifiers with DC control, developed for use in
monitors. The main differences between MM1207XD and MM1205XD are video amp bandwidth and output
rise time, and output fall time. Other characteristics are the same.

MM1207 is described here as the representative model.
MM1207 is a wideband video amps system developed for use in high resolution RGB monitors. In addition to
three matched video amps, it has a gate controlled differential input black level comparator for luminance
adjustment, three matched DC control attenuators for contrast adjustment, and three gain trimming CD
control subcontrast attentuators for white balance. All DC control input is high impedance, and the operating
range is set for easy interface with serial bus control systems, at 0~4V. Also, MM1207's built-in blanking
circuit clamps video output to between GND~0.1V during blanking, enabling blanking on the CRT cathode.
