We have a design that uses the DP83865 and when doing our production testing on the DP83865 we are seeing some boards that will not establish a link and other boards that we are seeing receive CRC errors from the MAC. I have gone through the troubleshooting guide and looked at several signals and nothing is standing out as being an issue. One thing I notice is that when measuring the signals at the RJ45 connector using a 100 ohm terminator I am seeing the signal goes a little above 2.0V. Does the link pulse below look acceptable? What are some other steps we could do to help narrow down the reason causing the boards to fail?
