Differential input accepting single ended signal

I am using the ADN2917 differential output as single ended inputs into the HMC856 and HMC726.  The system is communicating at 10Gbps.  I don't have the option of using a clock buffer.  Can the circuit be connect like below? 



Adding note about the clock buffer

  • Hi Ahtran,

    Differential ADN2917 output specs are different from single ended HMC856 and HMC726 devices. You will need to review the VIH/VIL specs for chip being driven by the ADN2917 in differential mode wrt single-ended spec from HM856 and HMC716. We can connect to one single ended device at a time but it violates the spec when we connect to two single ended devices. In general AIN+ can be used for single ended operation, check the HMC726 datasheet for the connectivity.

    Thanks,

    Siva Kumar.
