How to use Si5351 #2 - Si5351 Library for WSPR on QRP Transceiver

I introduced two ways to use the Si5351 in the previous post.  and  experimented with two different methods of generating clocks on the Si5351. I want to use both methods together.

Learn how to use the Si5351 for use with QRP radios include uBITX ,WSPR Beacone, Anatenna Anaylyser and many rf tools

As I am familiar with the AD9850, I first tried the Si5351 in uBITX. feel that using the Si5351 is suitable for QRP radios.
