85 Mhz Rgb Video Amplifier System With On Screen Display (osd) - National Semiconductor

The LM1281 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 1024 x 768. The Video sec- tion of the LM1281 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 LM1281 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.
