Contact MSK for MIL-PRF-38534 Qualification Status
DESCRIPTION:
The MSK 641 is a wide bandwidth, high voltage color or monochrome CRT video amplifier designed specifically to
drive the cathode of today's most demanding high resolution CRT monitors. The MSK 641 is a transimpedance
amplifier capable of achieving a ±35V output voltage swing with an input current of ±10mA. The output of the
amplifier is DC biased at half the power supply voltage. Transition times in the range of 2.5nS enable the MSK 641
to drive 10nS pixels with ease and make it ideally suited for monitors with 1280 x 1024 or higher display resolutions.
The 9 pin single in-line bathtub package is pin for pin compatible with the LH3424 and CR3424 and is a replacement
for the high-rel versions of these devices with improved stability and thermal performance.

COMPLETE VIDEO SYSTEM
Figure 3 above shows how an MSK 620 and MSK 641 can be used to drive a 100MHz monochrome monitor. The video signal
is A.C. coupled through C1. The video output pin of the MSK 620 rests at approximately +3.9Vdc and the input of the MSK 641
should be D.C. biased at approximately +1.55Vdc. D1, D2, D3 and Q1 act as a level shifting stage to match the output of the
MSK620 and the input of the MSK641. R8 and R9 sample the output and feed it back to the clamping section of the MSK 620 for
black level control superior to simply sampling from pin 14 of the MSK 620.
