    Thank you.

  • HMC760 / HMC661 Minimum Clock Frequency Limitation?

    Hello Engineer Zone experts,

    If I could get your insights, what really limits the minimum clocking frequency of the HMC760 and HMC661? Is it just the hold-mode droop rate limiting their output to a maximum recommended hold time of 2ns or is there some…

  • interfacing HMC661 with Xilinx Rf SOC ADC

    I want to interface HMC661 with Xilinx Rf SOC ADC (evaluation board zcu111). 

    Output impedance of HMC661 is 50 ohms and Common Mode Output Voltage is 0 volts, 

    Xilinx document number DS926 (table 114) tells input on die termination of ADC = 100 Ohms and common…
