DESCRIPTION:
The MSK 1922 High Speed, High Voltage Video Amplifier is designed to directly drive the cathode of today's high
performance CRT's. The MSK 1922 has user adjustable contrast and brightness levels and also comes with a
blanking function. The MSK 1922 can be directly connected to many video sources including RS170, RS343 and high
speed video D/A converters. The MSK 1922 has an internal resistor-inductor designed for optimum bandwith. The
MSK 1922 is packaged in a hermetic 30 pin power flatpack that can be directly connected to a heat sink using
standard 4-40 screws.

NOTES:
1
+VCC = +15V, -VEE = -10.5V, VBLANK = VGAIN = VOFF = ±VIN = 0V, CL=10pF, TC=25°C unless otherwise specified.
2
This parameter is guaranteed by design but need not be tested. Typical parameters are representative of actual device performance but are for reference only.
3
∆V is defined as the difference between +VHV and the output.
4
Parameter is 100% tested on production devices.
