LMX2820: PSYNC function

Part Number: LMX2820

Hi,

Good day. I hope you are doing well.

Our customer would like to how to implement the PSYNC function if they need to phase sync more than one LMX2820. Is this possible? 

Looking forward to your response. Thank you.


Regards,

  • 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.
