Re: clocks on xvf3000 reference design
thank you a lot for your reply, this was very helpful.
to clarify my reasons, i was wondering if connecting Si5351 i2c to my main microcontrolelr (instead of xmos) would be a good idea. however looking at the source code made me think i better leave this as it is.
