Difference in configuration of HMC832LP6GE and HMC833LP6GE

Hi, 

The SPI is same so you can program the part by using the same interfacing code.

The PLL register maps are also identical but there are some differences in VCO register maps. You may need to change those settings. Please refer to datasheets for the differences.

Thanks kpeker for pointing out the differences.

By any chance can you please provide me a Sample C Code working with HMC833

Hi,

Sorry, we do not have C code for HMC PLLs.

Hi kpeker,

Thanks for the reply. By any chance in any other language like python etc. or any other.. so that usage becomes easy and we can finish prototyping fast... too much pressure here

Still waiting here from anyone in community who could provide the Code for HMC833 PLL

We have tried but the intended frequency is not coming out like we want 232M and instead we receive 127M

Hi Mohit,

You have the Raspberry PI code that interfacing with HMC832 well, right? All you need it to change VCO registers and perhaps some PLL registers depending on your configuration, system requirements. 

If you have any concern with your register settings, please copy and we can give a quick look.
