Hi ,
We have DS90UB954-EVM & DS90UB953 for developing the SerDes solution and successfully implemented on our platform. Currently,we want to use 4-port solution DS90UB960 to replace DS90UB954,but experience the no signal output from 960. I have check the datasheet of 954 and 960,the register settings are the same if just want to use one port(Port 1) for the test. So I am wondering if there is any settings different from 954? Attached the DS90UB954 settings. Thanks.
regards,
Sean
