KS2501
OSD PROCESSOR FOR MONITOR
1
OVERVIEW
The KS2501 is used to display some characters or symbols on
a screen of monitor. Basically, the operation is to control the
internal memory on chip and generate the R,G,B signals for
some characters or symbols. The R,G,B signals are synchro-
nized 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 I
2
C bus. All timing control signals including
the system clock are synchronized with the horizontal sync.
Therefore there is a PLL circuitry on chip.
