Table 1. Pin Descriptions Pin No. 1 2 3 Signal VSS_A VCO_IN VREF1 Active I/O Input Input Ground (Analog Part) This voltage is generated at the external loop filter and goes into the input stage of the VCO. 1.26 V DC Voltage from the Bandgap Reference. Connected to ground through a resistor to make .

Preliminary KS2508 OSD PROCESSOR FOR MONITOR OVERVIEW 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 synchronized 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 internal ROM. This stored data a.
