I have one DS90UB947 EVM board as serializer, and my PCB is mounted with DS90UB928 deserializer, When I connect EVM board with my PCB, the deserilizer is recognized as DS90UH926 by ALP. How to correct this? Also I tried to generate pattern from EVM board but deserializer cannot lock ?

Thank you for your reply.

Actually it's found out that there's a HW designe defect in my PCB, after the HW fixing, the deserializer type can be recognized correctly by ALP, also generated patthern can be locked by deserializer.
