    Hi Cedrick,

    Please see datasheet section 7.3.12 Phase Synchronization for Multiple Devices for more details on multi-device synchronization. The PSYNC is re-timed by the OSCin signal, so if multiple devices share an in-phase OSCin clock, and both PSYNC pin signals meet setup and hold time on the same OSCin cycle, both devices can be simultaneously synchronized.
