arria 10 use transciever phy ip
hi,everyone,i have a issue about transciever phy ip,as follows:
the phy ip is 2 recieve channel,but the rx_is_lockedtoref signal of ch1 is unstable, ch0 is ok.
At the same time,i have a phy ip is 1 recieve channel to test the ch0 and ch1, all off them is ok,What is the problem?
Hi smile123,
When CDR is in locked to data mode, the status of rx_is_lockedtoref is unknown; it can be high or low or toggling. You do not need to care about rx_is_lockedtoref when rx_is_lockedtodata is high.

Hi,
you agree that you are not giving much info about your design?
As a starter question, does your design meet timing? Do you see any warnings, e.g. related to PLL usage?- smile123
