Tool/software:
1.) I have my design setup exactly like the DP83TG720 Media Converter module. The question is what is the physical layer end to end delays on the converter as far as data sent from one end of the PHY (720) to the other end of the PHY (867)?
2.) Can an 802.1AS packet go thru the current implementation properly (DP83867/DP83TG720)?
Hi Adam,
1) You can use the receive/transmit latency specifications from the DP83TC720 and DP83867 data sheets.
720:
867:
Note 867 has different sections for SGMII and RGMII latency. Excerpt below is from RGMII .
2) Yes, it can go through this media converter module correctly.
Thanks,
Drew
So if the signal comes from the automotive Ethernet transmit and thru media converter to Standard Ethernet what is the min delay and max delay based on the parameters? Can you give me values here?

Would the latency values below be correct on the data flow? Or is there more latency to account for in the end to end transmission?
