Abstract: Methods and apparatus for synchronization of integrated circuits (ICs) within a wireless network. In one embodiment, a serial time protocol (STP) is disclosed for use within a wireless device of a wireless network. The disclosed STP provides a common protocol for communicating precision time information from one time-transmitter IC to another time-receiver IC within a wireless device. In one exemplary implementation, a time-transmitter and a time-receiver are implemented within the firmware of a wireless device. Various schemes utilizing the disclosed STP for time synchronization are also described.
