• How to set the register of HMC1032 to use it in integer mode?

    Hi, 

    I set the registers to get 250 MHz output for integer mode, shown below. My reference is 10MHz.  However, I could not get the integer phase noise graph same as that in the datasheet of HMC1032. The phase noise I measured is more looks like fractional…

  • FAQ: HMC PLL with Integrated VCO AutoCal with High N Counter/Low PFD Frequency

    Question:

    With an HMC PLL with integrated VCO (e.g. HMC1033) when using a high N counter value, say N > 4000 (such as when the PFD frequency is low), the PLL does not always function with VCO auto calibration (autocal). How do I get the PLL  to lock…
