application diagram of HMC547ALP3E

what are the values of the external  resistor and capacitor for pins 10 and 11? or should I use two 100ohm resistors as explained in the evaluation board?

  • Hi Rids,

    In the datasheet, the resistor and capacitor shown in the interface schematic is a representation of the internal circuitry, connecting to the digital pins, A and B (pin 10 and 11).

    On our evaluation board, we populate external 100 Ohm resistors on the digital control lines in the R1 and R2 spots.
