DESCRIPTION:
The MSK 620(B) is a very high frequency video amplifier system capable of driving displays with resolutions up to
1664 x 1200. Brightness is controlled with a gated differential input black level clamp comparator. There are also DC
inputs available for contrast control and drive control. All DC control inputs operate over a 0V to 4V input range and
feature high impedance inputs. The MSK 620(B) is packaged in a space efficient hermetically sealed 18 pin dip
package.
