Hi Jim, Thanks, I'm investigating this further. I've supplied the ADC clock, and wrote the proper digital reset bit, and I can now read and write to any register. I triggered sysref over spi via the method described in section 9.3.2.1.1 of the lmk04828 datasheet. However, I'm still having the 500mV issue. I know my power sequencing may be an issue right now (which I'm going to try and fix tomorrow). However, that should just effect the default registers correct? Or does that entirely wreck all known behavior? I'm pretty stuck on this read back right now, since it requires me manually decoding over a scope instead of with my logic analyzer Thanks for all the help, -Jake
