Integrated Circuit
Advanced Monitor Video Controller
Description:
The NTE7137 is a monolithic integrated RGB amplifier in a 20–Lead DIP type package designed for
color monitor systems with super VGA performance. It is intended for DC or AC coupling of the color
signals to the cathodes of a CRT.
Features:
D Fully DC Controllable
D 3 Separate Video Channels
D Input Black Level Clamping
D White Level Adjustment for 2 Channels Only
D Brightness Control with Correct Grey Scale Tracking
D Contrast Control for All 3 Channels Simultaneously
D Cathode Feedback to Internal Reference for Cut–Off Control, Which Allows Unstabilized Video
Supply Voltage
D Current Outputs for RGB Signal Currents
D RGB Voltage Outputs to External Peaking Circuits
D Blanking and Switch–Off Input for Screen Protection
D Sync On Green Operation Possible
