I have an AD9739A-FMC-EBZ and jumpers JP1 and JP2 are not installed.  Why is that?  Thank you.

Why are jumpers JP1 and JP2 not installed on the AD9739A-FMC-EBZ Rev C evaluation board I purchased.  It seems like there is no power to the board without these jumpers.

Thank you for your help!

  • I have noticed on the Rev A board J17 was used for external power to the AD9739A-FMC-EBZ.  Then on the Rev B board J17 was deleted and the power comes in through the FMC connector.  It looks like Rev C is also only powered via the FMC connector.  However, Rev A, Rev B, and Rev C all have jumpers labelled JP1, JP2, etc but these are not called out on the Bill of Materials.  Is there some other option for powering the Rev C board other than the FMC connector?  If not, are the missing jumpers JP1 and JP2 on my Rev C boards simply a mistake in manufacturing and need to be added for the board to operate?  Thank you for your help!
