How to synchronize a PXIe 6356 card usind a PXI 1042q chassis with 10 MHz external clock

Hi,

here the problem, I have a PXIe 6356 card mounted on a PXI 1042q chassis. On the REf in of the PXI chassis I have routed in a REF 10 MHz that comes from an atomic clock. 

I have to use 6 AI of the 6356 and I would like to know how I can be sure that the time base used by the card is the REF 10 MHz I routed in. From the manual seems the 6356 can Phase locked only to 100 MHz. Can I use as time base for my acquisition an external 10 MHz ?

Thank you in advance for your help,
