Abstract
A first PHY may be coupled to a second PHY via a network link. The first PHY may transition from a role of timing master for the network link to a role of timing slave for the network link. During a first time interval subsequent to the transition, the PHYs may communicate half-duplex over the link while the first PHY synchronizes to a transmit clock of the second PHY. During a second time interval, the PHYs may communicate full-duplex while the second Ethernet PHY synchronizes to a transmit clock of the first PHY. Also during the second time interval, the first PHY may determine that the first PHY and the second PHY are synchronized. Subsequent to the determination, the PHYs may begin full-duplex communication of data on the network link.
