SJA1105 Ethernet latency

[stephanernst]

I don't find informations in the datasheets of the Automotive Ethernet Switch SJA1105 about Ethernet Latency. I measure about 80us, but is that a realistic number?

Where can I find performance data like this?

I'm interessted in latency with variable packet sizes.

80uS can be realistic or non-realistic, depending on how
you measured it. Strictly speaking, frame latencies are not specified because they depend on
multiple factors. Some discussion of the latencies you should expect can
be found in AH1704, Section 8. The document is available on  Docstore

Have a great day,
