OSD PROCESSOR FOR MONITOR
S5D2508A01
OVERVIEW
The S5D2508A01 is used to display some characters or sym-
bols on a screen of monitor. Basically, the operation is to con-
trol the internal memory on chip and generate the R,G,B signals
for some characters or symbols. The R,G,B signals are syn-
chronized with the horizontal sync. Then the R,G,B signals are
mixed with the main video signal in the Video Amp IC.
The font data for characters or symbols are stored in the inter-
nal ROM. This stored data are accessed and controlled by the
control data from a micro controller. The control data are trans-
mitted through the I2C bus. All timing control signals including
the system clock are synchronized with the horizontal sync.
Therefore there is a PLL circuitry on chip.

Character Height Control
Two examples of the height-controlled character are shown in the following figure. The height control is performed
by repeating some lines. The repeating line-number comes from the equation below.
[# of the repeating lines = 2 + N × M ] ,
where N = 1,2,3,... and M = round{14÷(CH[5:0]-18)}.
If the M value is less than or equal to 1, all the lines of the standard font are repeated once or more. This is
described as following.
(i) If CH[5:0] is greater than 32, and less than or equal to 46 (32 < CH[5:0] ≤ 46), then all lines are repeated once
or twice. The lines repeated twice are selected by the following equation.
[# of the repeating lines = 2 + N × M ] ,
where N = 1,2,3,... and M= round{14÷(CH[5:0]-32)}.
(ii) If CH[5:0] is greater than 46, and less than or equal to 60 (46 < CH[5:0] ≤ 60), then all lines are repeated twice
or three times. The lines repeated three times are selected by the following equation.
[# of the repeating lines = 2 + N × M ] ,
where N = 1,2,3,... and M= round{14÷(CH[5:0]-46)}.
iii) If CH[5:0] is greater than 60, and less than or equal to 64 (60 < CH[5:0] ≤ 64), then all lines are repeated three
or four times. The lines repeated four times are selected by the following equation.
[# of the repeating lines = 2 + N × M ] ,
where N = 1,2,3,... and M= round{14÷(CH[5:0]-60)}.
The repeating line-number is limited to 16.
