Other Parts Discussed in Thread: ALP, USB2ANY
I have been trying to use the ALP Margin Analysis tool to validate our DS90UB960 design but I am facing some problems. My setup is composed by our ECU, which includes the DS90UB960, and DS90UB953EVM on the other part of the video link. I connect via USB directly to the DS90UB953EVM, and to the DS90UB960 through the backchannel. Seems that the connection is OK because I can detect both SER and DES on the ALP.
I am using PORT 0 to do the Margin Analysis, but I am always obtaining red results in all EQ/SP positions.
Additionaly, when I perform Margin Analysis test, I loss the communication on the link utill I restart the board.
I also tryied to use a DS90UB960-Q1EVM with the same results (using both EVM).
Last test I have done is changing the coax cables. Same result.
Do you have any idea that what is happening? Could be a configuration problem?
Thank you in advance.
