MM1205XD

MITSUMI 85MHz RGB Video Amplifier/130MHz RGB Video Amplifier MM1207, 1205 85MHz RGB Video Amplifier/130MHz RGB Video Amplifier 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. Model Video amp band Output rise time Output fall time MM1207 85MHz 4.3nS 4.3nS MM1205 130MHz 2.6nS 3.6nS 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. Features 1. 2. 3. 4. 5. 6. 7. 8. 9.
