AD9517 reference clock ac-coupling

I'm facing problems with the AD9517-1 reference clock inputs.

I want to ac-couple a reference clock into REF2, but when I read back register 0x001f, I always get 0x08. The clock is not recognized by the monitor. From the data sheet I get that the clock has to be above 20MHz and 800mV p-p. Is this correct?


The monitors are turned on, as well as the single ended inputs (0x001b = 0xe8 and 0x001c = 0x06)


Thank you very much for your help!
