AD-FMCOMMS SPI Clock Rate

Question asked by daniel.nauth Employee on Oct 21, 2014

It looks like the SPI interface on the AD-FMCOMMS reference designs is configured somewhere around 5 MHz, but it appears the AD9361 can support up to a 50 MHz SPI clock. Has anyone tried bumping the SPI clock up in speed on the reference design? Is this easily done, or does it break other timing relationships in the reference design? Any help or advice is appreciated.

 

Thanks!
