OSD PROCESSOR FOR MONITORS
KS2501
OSD PROCESSOR
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 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
transmitted through the I2C bus. All timing control signals
including the system clock are synchronized with the horizon-
tal sync. Therefore there is a PLL circuitry on chip.
FEATURES
• Built-in 1 Kbyte SRAM
• 464 ROM fonts (448 standard fonts + 16 Multi-color fonts)
• Full Screen Memory Architecture
• Wide range PLL available (15kHz ~ 120kHz)

• Character color selection up to 16 different colors
• Programmable background color (Up to 16 colors)
• Character blinking, bordering and shadowing
• Color blinking
• Character scrolling
• Fade-in and fade-out
• Row to row spacing control
• Window outline and shadowing
• Box drawing
• Character sizing up to four times
• 8 PWM DAC channels with 8-bit resolution
• 96MHz pixel frequency from on-chip PLL
