Yes, but...
I'm waiting to see how they solve the output math relation in the shared PLL.
The etherkit Si5351arduino lib from Jason claims it can put two freqs sharing the same PLL if below certain point, my tests show that that's true ONLY if you don't move them...
Once you start to move one of the two in the shared PLL (VFO, correction, sideband change) the other will start jumping... BTDT... (in my case the jumps was from a few 100th of Hz to a few KHz)
My lib always use integer math to minimize jitter and phase noise (bad things on RF), but that has the side effect of no PLL sharing, then the 2 of 3...
But you know, there is no silver bullet... at least for free or very cheap... ;-)
I'm waiting to see how they solve that...

2 of 3 may be a problem for the uBitX. It uses all three clocks.

Hi group, I'm back.
Do you rememeber the pull request to switch from the etherkit Si5351 lib
(from NT7S) to my new Si5351mcu?
After a tough revision of the code I found that the error that make the
code a no-go was related two main factors:
* I2C initialization.
* Human error.
I develop mainly on the house desktop PC but use the laptop to connect
and upload the code to the internet; this resulted in wrong (incomplete)
code uploaded to the github repository. (shame on me.)
A bug on the correction procedure was found & fixed, the init procedures
are now mandatory and a general update to the documentation on the code
coments and Readme.md was made.
A new version (0.3) of the Si5351mcu library for arduino and flavours
was pushed to the github repository a minute ago
() you can just click the green
download button or go to the releases tab and grab it from there.
I have the bitx40 code now working back in home with a real Raduino +
Bitx40v3 SMD, but it's working against Allards code version 1.13, I will
update it tonight against lastest 1.14.1 and fill a push request tomorrow.
Firmware & sram reduction waranted.
