Integrated Circuit
Advanced Monitor Video Controller for OSD
Description:
The NTE7138 is an RGB pre–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:
85MHz Video Controller
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
On Screen Display (OSD) Facility

Note 1. Signal amplitude of 50mA black–to–white is possible if the average current (including blank-
ing times and signal variation against time) does not exceed 50mA. The maximum power
dissipation of 1200mW has to be considered.
Note 2. Equivalent to discharging a 200pF capacitor through a 0
series resistor.
