Hi Group,
I did seen the questions about the Si5351 now and before (did read your mail Rob).
The Si5351 is also a good oscillator in some cases and can be used with my firmware I expect. The firmware also support on the moment the Si570, Si549 and the AD9850 with compile options so the Si5351 can also included. The attiny84 chip is used because he is Tiny. Other AVR chips like the atmega328 can also be used (I did run it on a softrock some time ago) to run with some more space.
The firmware source and all the protocol documentation is on my website
Have a nice day!
