Preliminary
TUNNING FACTORS OF THE KB2502 PLL
PLL External Circuit
You may follow the recommendations for PCB art work and input/output signal characteristic improvement in
recommendation.
The external circuit that has the most influence on KB2502 PLL block operation is pin 3 (VCO_IN) and pin 4
(CP_OUT)'s surrounding circuit. Refer to OSD PLL block.
Because the PLL circuit is basically a feedback circuit, there are many components that influence the
characteristics. C1, R1, R2, and R3 do not have a localized effect.
As you can see, they are connected to the PLL control bits and influence the characteristics through their
complicated relationships. The main functions of the time canstant and their reference values are as follows.
