LM1283
140 MHz RGB Video Amplifier System with On Screen
Display (OSD)
General Description
The LM1283 is a full feature video amplifier with OSD inputs,
all within a 28-pin package. This part is intended for use in
monitors with resolutions up to 1280 x 1024. The video sec-
tion of the LM1283 features three matched video amplifiers
with blanking. All of the video amplifier adjustments feature
high input impedance 0V to 4V DC controls, providing easy
interfacing to bus controlled alignment systems. The OSD
section features three TTL inputs and a DC contrast control.
The switching between the OSD and video section is con-
trolled by a single TTL input. Although the OSD signals are
TTL inputs, these signals are internally processed to match
the OSD logic low level to the video black level. When ad-
justing the drive controls for color balance of the video sig-
nal, the color balance of the OSD display will track these
color adjustments. The LM1283 also features an internal
spot killer circuit to protect the CRT when the monitor is
turned off. For applications without OSD insertion please re-
fer to the LM1205 or LM1208 data sheets.
