Abstract:
System and method for synchronizing a plurality of nodes to a timing signal using a daisy-chain network having a forward transmission path and a reverse transmission path connected at a midpoint. Latency of the timing signal to the midpoint of the daisy-chain network is determined, a respective latency of the timing signal from the node to the midpoint of the daisy-chain network is determined, and a respective timing offset for each of the plurality of nodes is calculated. A local time-of-day counter at each of the plurality of nodes is adjusted based upon the respective timing offset of the node to synchronize the plurality of nodes to the timing signal.
