Hi, Dong,

The expert comment is:

1) What models is the customer using (for both driver and receiver)? Is this a read simulation or write simulation?
2) Does the customer have the waveform that illustrates the failure?
3) Has the customer followed the datasheet layout guidelines? Has their layout been reviewed by TI?

Regards,
Mariya
