Hi,

My customer is using TLK2711-SP.
He has below questions about behavior of RKMSB and RXCLK during power down mode period.
Could you answer below questions, please?

Q1:If LOS detection is not detect during power down mode period, Does RKMSB outout High?

Q2:Does RXCLK operate during power down mode period?

Best regards,

Hi Shimizu,

A1. If the device is disabled (power down mode), RKMSB will reflect the status of LOS indicator, not necessary a high state.

A2. RXCLK does not operate during power down period.

Hi Luis,

Thank you for your support.
I add a question about your answer "A2".

Does your answer "A2" mean "High impedance"?

Best regards,
Shimizu

Hi Shimizu,

You are right, if the device is disabled (ENABLE=L) then RXCLK will remain in high impedance state.

Luis
