Abstract
A network node device of an area network includes physical layer (PHY) circuitry configured to transmit and receive frames of data via a communication link of the communication network; medium access layer (MAC) circuitry; a receive interface between the PHY circuitry and the MAC circuitry, and timestamp circuitry. The receive interface includes a receive clock signal and a DLL. The timestamp circuitry is configured to produce multiple sample signals derived from the receive clock signal using the DLL and a local clock signal of the network node, and produce a timestamp offset using the multiple sample signals. The timestamp offset is representative of an instantaneous phase offset between a local clock of the network node and a local clock of a neighbor node of the network node.
