LMK03806: The register meaning of the LMK03806

Part Number: LMK03806

Hi team,

My customer use the LMK03806 to provide the clock for the PCIE.

And they find sometimes the initialization of the PCIE will failure. After some debug, they suspect the issue is because of the long delay of the clock provided by the LMK03806. And they compare register of the good one and the failure one, find the register value of R17, R18 and R19 are difference.

For the failure one, the register value are as below:

R17:0x8002c80

R18:0x2c00000

R19:0x99050000

1. because I can't find the meaning of the R17, R18 and R19 register in datasheet. Can you help to provide?

2. Have you ever encounter the issue about long latency in LMK03806. what may be the cause for this?

 

Thanks a lot!
