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.

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.
Features
1. Built-in wideband video amp
110MHz @ -3dB (4VP-P output)
2. OSD input has TTL interface
bandwidth 50MHz
3. Output voltage less than 0.1V for blanking
4. High-speed switching between VIDEO/OSD
5. Each channel has an independent drive pin for color balance adjustment
6. Built-in high impedance DC contrast control, 0~4V (> 40dB range)
7. Built-in high impedance DC drive control, 0~4V (±3dB range)
8. Built-in high impedance DC OSD contrast control, 0~4V (> 40dB range)
9. 7VP-P output swing (band slightly attenuated)
10Output can drive hybrid or discrete CRT drivers directly
Package
DIP-28C (MM1381XD, MM1382XD, MM1383XD)
Applications
1. High resolution RGB CRT monitors with OSD function
2. AGC amps for video
3. Gain and DC offset control
4. LCD or CCD system interface amp
