hi,




I want to use 8 LTC2107 @ 204MSPS with synchronized data sampling.


Is there any extra requirements for schematic design other than the same sampling clock?


I noticed that LTC2107 doesn't have other special pins for synchronization.




best regards




Xiang

    Hi,
    

    Thanks for using the LTC2107.
    

    Unfortunately, multi-chip sync is not supported on this chip. You will need to have the same clock source for all the 8 ADCs. Make sure that there's no significant delay on the clock inputs for all ADCs (length matching) and the clock source can drive properly all the 8 ADCs clock input.
    

    Regards,
    

    Mark
