M52780-XXXSP
I2C BUS CONTROLLED 3CH VIDEO PRE-AMP WITH OSD CONTROLLER FOR HIGH RESOLUTION COLOR DISPLAY
MONITOR
DESCRIPTION
M52780 - XXXSP is the I2C BUS controlled Semiconductor Integrated
Circuit with 150MHz range 3ch Amp and Letter Indication Controller which
function in range 30MHz~80MHz.
VIDEO Pre-Amp includes ,in each channel , Retrace Blanking, Wide Range
Amp,Brightness Control,and Bus Controlled Main Sub Contrast ,OSD Adjust
Control,5ch D/A Output,and OSD Controller.
Letter Indicate Controller can indicate Characters,such as Chinese character ,
Hiragana letter , Katakana letter ,English letter , Number letter , and so on.
Therefore it is the most suitable for High Resolution Display Monitor.
