The 7705 SAR can receive and extract time of day/phase recovery from a 1588 grand master clock or boundary clock and transmit the recovered time of day/phase signal to an external device such as a base station through an external time of day port, where available. Transmission is through the ToD or ToD/PPS Out port with a 1 pulse/s output signal. The port interface communicates the exact time of day by the rising edge of the 1 pulse/s signal.
