LMK03328: How to debug PLL Loss of Lock

Part Number: LMK03328

Hi Team,

I am having a problem that the PLL Loss of Lock.

It is known that the output of the N divider is stopped.

(Depending on the output of the STATUS0 pin set by R27 [7: 4]=0x4)

The outputs of the R divider and M divider are working normally.

(Similarly, depending on the setting of R27(R28))


How should we debug from here?

WEBENCH data will be attached
