LMK04808BEVAL: Status of clkin0

Adrian Liu

Part Number: LMK04808BEVAL
Other Parts Discussed in Thread: LMK04808

Hi Team,

Customer is testing the LMK04808 EVM and wants to determine whether clkin0 is present. However, the status level of clkin0 does not change when there is no reference.

Could you help check the config?

Hi Adrian,
Can you attach customers .tcs (config) file?

Regards,

Vicente

Hi Adrian,

I couldn't find anything out of the ordinary with the config you provided. I will look into this further tomorrow.

Hi Adrian,
When I import the the config you provided to the LMK04808EVM, I get that both VCO frequencies are outside the ranges of operation.

Could you attach a .tcs file instead? I just want to be sure the configuration I have is correct.

Regards,

Vicente

Hi Vicent,

Here attached the tcs file.

The lock status is normal, but the clkin0 level did not change with / without input.

Please help check it.
