DATA SHEET
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.

OSD part data input (Sequence)
(a) Sub addresses are consists of 16 bits.
(b) Data is consists of 16 bits.
(c) Sub addresses and data are communicated in 8-bit units. Input the
lower 8 bits before the upper 8 bits. Make input from the MSB
side.
(d) After the start state has been attained and the control byte
(7CH) received, the next 16 bits (2bytes) are for inputting the
address. Addresses are increased in increments for every 16
bits (2 bytes) of data input thereafter. As a result, it is not
necessar
to input the address from the second data.
