Part Number: TLK10034
In our design we have used TLK10034 in (XAUI <-->10G Base-KR mode), 4x 10G Base-KR channels are connected to an External Switch (residing on the same PCB). 4x XAUI channels are connected to a XAUI switch. The 4x XAUI channel links are UP. But 10G Base-KR side link is not UP. Auto Negotiation is not completing with value of AN_STATUS register (0x7.0x1) toggling between 0x88 and 0xCD .The Auto Negotiation is not completed on the Link Partner side also.
What might be causing this?
In reply to NARENDAR REDDY VYR:
Unfortunately we are limited in the support provided for this device issue. I can say that the toggling is caused by link drop in auto negotiation. Device appears to be reporting LOS condition which is only possible if the criteria in the data sheet are met.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

Hi Malik Barton,
We were able to make the link up.We have set "KR_TRAINING_ENABLE" bit .i.e. Bit 1 to "0"(Device Address: 0x01, Register Address: 0x0096, Value: 0x0000 , Disable 10GBASE-KR start-up protocol ).
Then the 10G Base-KR Link started coming-up.
Some times we may need to give data path reset .i.e. make Device Address: 0x1E, Register Address:0x000E , Value:0x0008. We have to check whether we really need to give data path reset after disabling of KR Training.
