The Atom GNSS module uses a built-in GNSS Receiver module to receive satellite signals from GNSS antenna and output 1PPS GNSS frequency signals.
The Atom GNSS module uses a built-in frequency PLL module to trace and lock 1PPS phase and frequency and output the system clock.
The Atom GNSS module uses a built-in APLL module to multiply the system clock to a clock at GE rate which is then used as the SyncE transmit clock.
The device uses the GE interface to obtain SyncE clock signals from the Atom GNSS module and transmits the clock signals to downstream devices.
The Atom GNSS module uses a built-in GNSS receiver to receive satellite signals from GNSS antenna and output the UTC time.
The Atom GNSS module uses a built-in time PLL module to trace time PLL, lock the UTC time, and output the system time.
The Atom GNSS module uses a built-in time RTC module to obtain the system time.
The Atom GNSS module uses a built-in PTP GM module to process PTP messages. The timestamps carried in PTP event messages are generated by the RTC module.
The device uses the GE interface to obtain PTP time signals from the Atom GNSS module and transmits the time signals to downstream devices.
