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.

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 necessary to input the address from the second data.

DISPLAY FORM 2
M52780SP has the following four display forms.
(1) Character size : Blanking same as the character size. (2) Border size : Blanking the background as a size from character. (3) Marrix-outline size : Blanking the background 12 X 18 dot. When set register BETA14 to "1", setting of blanking the background 14 X 18 dot is possible. (4) All blanking size : When set register BCOL to "1", all raster area is blanking.

CHARACTER FONT
Images are composed on a 12 X 18 dot matrix, and characters can be linked vertically and horizontally with other characters to allow the display the continuous symbols.
12 dots
18 dots
When the character extends to the top line of the matrix, no border is left at the top.
When the character extends to the bottom (18th) line of the matrix, no border is left at the bottom. Note : Hatching represets border.
Example for displaying a continuous pattern after combining characters in the horizontal or vertical direction Character code FFH is fixed as a blank without background. Therefore, you cannot register a character font in this code.

Application Method
CLAMP PULSE INPUT Clamp pulse width is recommended above 15 KHz, 1.0 sec above 30 KHz, 0.5 sec above 64 KHz, 0.3 sec .
The clamp pulse circuit in ordinary set is a long round about way, and beside high voltage, sometimes connected to external terminal, it is very easy affected by large surge. Therefore, the Fig. shown right is recommended.

Notice of application * Make the nearest distance between output pin and pull down resister. * Recommended pedestal voltage of IC output signal is 2V.
