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.

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. Built-in wideband video amp 85MHz @ -3dB (4VP-P output)

2. Matched (±0.1dB or 1.2%) contrast adjustment attentuators built-in

3. Built-in cutoff and luminance adjustment single end input comparators with external gate control

4. Gain of each video amp controlled independently

5. Built-in high input impedance DC contrast control, 0~4V (> 40dB range)

6. Built-in high input impedance DC drive control, 0~4V (±3dB range)

7. 7V_P-P output swing (band slightly attenuated)

8. Output blanking function

9. Output can drive almost all hybrid or discrete CRT drivers directly

Package

DIP-28B (MM1207XD, MM1205XD)

Applications

1. High resolution RGB CRT monitors

2. AGC amps for video

3. Gain and DC offset control

4. Interface amps for LCD or CCD systems
