Overview: MITSUMI RGB Video Amplifier with OSD Input MM1381, 1382, 1383 RGB Video Amplifier with OSD Input Monolithic IC MM1381, 1382, 1383
Outline
MM1381XD, MM1382XD and MM1383XD are wideband RGB video amplifiers with OSD input, developed for use in monitors. The main differences between them are video amp bandwidth and output rise time, and output fall time. Model Video amp band Output rise time Output fall time MM1381 85MHz 3.5nS 4.5nS MM1382 110MHz 3.0nS 4.0nS MM1383 140MHz 2.3nS 3.3nS MM1382XD is described here as the representative model. MM1382 is a wideband video amp system with OSD input, developed for use in high resolution RGB monitors. MM1382 has three matched video amps with a blanking function. All DC control input is high impedance, and the operating range is set for easy interface with serial bus control systems, at 0~4V. The OSD section has three TTL inputs and DC contrast control. OSD signals have TTL input interface, and these signals are made internally so that OSD input low level and video black level are the same. OSD display color balance follows video signal color balance control adjustment. In addition, MM1382 has a built-in spot-killer circuit that protects the CRT when monitor power is turned off.
