DP83867IRPAP-EVM: Which EVM can be used for GMII and RGMII interface ?

Other Parts Discussed in Thread: DP83867CS, DP83867IR,

Hello

　Customer is considering to use DP83867CS and DP83867IR. 

Interface is GMII or RGMII.

1. Can we use DP83867IRPAP-EVM for GMII evaluation as DP83867IR and RGMII evaluation as DP83867CS ?

2. Do you have errata for those devices?   I could not find on TI.com. 

3. Can DP83867 identify reason for link error?

・ In this case, it is assumed that the link is not broken due to external noise
・ Only when the link of the PHY device breaks due to S / N ratio.

Best regards,

    Hello,

    You can use this EVM to evaluate RGMII and GMII through straps or register configuration. However, keep in mind this EVM uses the 64 pin package while the DP83867CS is in the QFN package.

    I will follow up on the errata for you.

    Can you provide more context for this error? Where was this reason derived from?

    Thank you very much,

    Cecilia
