MM1381XD

The MM1381XD is one member of the MM1381 family which is designed as the RGB video amplifier with OSD input that can be used in (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. And this device 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 to 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.

Features of the MM1381XD are:(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  djust-ment; (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 to 4V (> 40dB range); (9)7VP-P output swing (band slightly attenuated) (10)Output can drive hybrid or discrete CRT drivers directly.

The absolute maximum ratings of the MM1381XD can be summarized as:(1)storage temperature: -55 to +150 °C;(2)power supply voltage: 15.0 V;(3)input voltage range: GND <= VIN <= VCC V;(4)video output current: 28 mA;(5)allowable loss: 2.5 W;(6)electrostatic breakdown: 2 kV;(7)pin temperature:256 °C.
