OSD PROCESSOR FOR MONITOR

OVERVIEW

16-DIP-300

The KS2508 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 C bus. All timing control signals including

the system clock are synchronized with the horizontal sync.

Therefore there is a PLL circuitry on chip.
