Intel: If the other device is reset during data communication and data is interrupted, is it necessary to take any measures such as inserting rx_analogreset, performing recalibration, resetting the entire transceiver, etc.?
Category: Walkie Talkie
tool:-
Device: Stratix® 10
If such a situation occurs, a Transceiver Reset is required to ensure that incoming Data is locked after communication is restored.
If the peer device is reset and the received data is interrupted, it is expected that the CDR lock will be lost.
This operation corresponds to "module connection" and "RX CDR lock mode change" in the "Reset Conditions" below, so it is recommended to perform the Reset sequence.
