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.

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)

10. Output can drive hybrid or discrete CRT drivers directly

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
