NTE7137
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:
Fully DC Controllable
3 Separate Video Channels
Input Black Level Clamping
White Level Adjustment for 2 Channels Only
Brightness Control with Correct Grey Scale Tracking
Contrast Control for All 3 Channels Simultaneously
Cathode Feedback to Internal Reference for Cut–Off Control, Which Allows Unstabilized Video
Supply Voltage
Current Outputs for RGB Signal Currents
RGB Voltage Outputs to External Peaking Circuits
Blanking and Switch–Off Input for Screen Protection
Sync On Green Operation Possible
