DP83867IR: Max RGMII 1000M latencies for DP83867

Vincent Leboeuf

Part Number: DP83867IR

Tool/software:

Hi,

In the datasheet of DP83867IR/CR, the latencies of the RGMII (1000M) are given as nominal values: 88ns for TX and 288ns for RX.

What are the maximum guaranteed values?

Best regards,

Vincent

Hi Vicient,

I check with the design team internally. I seems like the nominal value is latency is actually the maximum latency of DP83867. The reason why we put it as nominal latency because of the small sample size.

Thank you for your answer.

The datasheet date is Feb. 2015. Can you propose a more recent reference, with max latency guaranteed?

Thank you.

Hi Vincent,

Sorry for late response. I confirm the data with the team internally.

Apparently, the information in the datasheet is what we have for DP83867.
