    Thread Summary
    
                The user is connecting the differential output of ADN2917 to the single-ended inputs of HMC856 and HMC726 at 10Gbps without a clock buffer. DC coupling is not possible, and AC coupling capacitors and pull-up resistors are required to ensure proper operation without affecting data rates. The user should refer to the ADN2917 datasheet for AC coupling capacitor selection and verify the HMC726 datasheet for single-ended connectivity.

    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?
