Other Parts Discussed in Thread: DP83825I

Hi,

I've a couple of answers about DP83825I eth phy:

is possible to know TYP. and MAX. propagation delay times low-to-high and high-to-low of both TX and RX paths from RMII to physical medium? or at least total loop delay?
is possible to disable RX FIFO buffer at all?

I've not found it on datasheet.

Regards,

Marco

Hi Marco,

The DP83825 is still under development and the data on the web is advance information. I will cycle back to you with more updates but in the meanwhile can you share details on what is the end equipment and how this information will be used?

We are evaluating to use it to interface our device to a real-time industrial bus (like EtherCAT, Powerlink, etc.) and deterministic latency time and its variations are important in terms of total cycle time.

Many thanks, I'll wait your for more informations.

Best regards
Marco
