On behalf of a customer:
Our application doesn’t require a great deal of data. Frames of, say sixteen bytes would work well. The shorter the frame the sooner we get the CRC/FCS and can run with the result.
Is there a specification that specifically calls out a minimum frame size for this device (i.e., not a generic Ethernet/IEEE 802.3/IEEE 802.3ab)? Other minimums (preamble duration, IPG) that might give us better performance than if we stick with formal, switchable Ethernet? (Our application is always point-to-point, and the MAC functionality is in the programmable logic.)
Experimentation says that we can cheat these way down, but I’d rather rely on a spec, just not the 802.3 because I don’t care about interoperability, only DP83867IR-to-DP83867IR.
Is there any documentation that shows the smallest frame size the DP83867IR will support, even if not compliant with IEEE 802.3?
Thanks, -Steve
