HMC830

Hello,

 

I have the Evaluation Kit for the HMC830LP6GE PLL with Integrated VCO and an external reference of 100 MHz. I'm running the the HMC PLL software version V3240.exe. The program appears to work fine, but when I tune to a frequency of 3GHz I get a deviation of 250Hz even though the software indicates that it should be exactly at 3GHz. My registers configuration values are are listed below. Any suggestions? Thanks and best regards.
