Hi,
I would like you to confirm which method is better for DP83867.
* According to following URL, there is description about timing budget of DP83867.
I read overview of above, and I understand there is description about how we can set delay in this document.
But I'm not sure which method is better to set delay.
A. At first, we do not add delay and just measure clock and data.
After that, we should add delay based on this result.
B. There is general delay value(Ex 2.0ns) which we should apply and we should set this delay value at first.
If user can not achive timing requirement, even though they set certain delay value, user should set additional setting.
The difference b/w above two is that this delay setting is "mandatory" or "option".
In RGMII mode, we would like to know whether this setting is mandatory or not.
Best Regards,
