Abstract:
A method for synchronizing a plurality of series coupled nodes is described. A master trigger is transmitted through the plurality of series coupled local nodes in a downstream direction from a first node to a last node and retransmitted through the plurality of series coupled nodes in an upstream direction from the last node to the first node. Then, a local synchronization time is calculated at each of the plurality of series coupled nodes based on a differential measurement between the arrival of the master trigger in the downstream direction and the upstream direction. Operations in the local nodes may be synchronized based on the local synchronization time.
