We are new with HMC769LP6CE Fractional-N PLL with Integrated VCO SMT, 9.05 - 10.15 GHz and we are need to use this device for a single frequency 9GHz phase locked.  As we are a microwave company we are bit thin on the knowledge of digital domain.  We have eval board for HMC769LP6CE.


1) In our circuit we have MCU ATMEGA328 which will write the word and set the registers on start up.  Can you help is with setting the registers.

2) Based on the datasheet would it be sensible to use passive filter.


It is the word writing we need help in and how can we confirm if the registers are set correctly.


urgent attention would be appreciated
