Part Number: LP-AM243

Hi Team,

There's an issue from the customer need your help:

we use 3 LP-AM243 in a EtherCAT network to test DC Sync0 signal, from the oscilloscope the sync0 signal have a large difference and more than 600ns.

Is it normal in PRU-ICSS?? thank you

660ns is our process path latency ! Could you share the master, topology and any wireshark logs during the measurement. It looks like delay compensation is not done by the master correctly
