True for the first frequency. The second statement may or may not be true,
it
was not clear in the original description of the device. When I wrote Leo
and
asked about a specific second frequency he did a manual calculation and sent
me
the parameters. From another email reply:
"Sorry, did not catch your email first time. Thank you for your custom!
The numbers are internal settings of PLL chip Si5328 and you can find
more
details here:
https://www.silabs.com/Support%20Documents/TechnicalDocs/Si53xxReferenceManual.pdf
You can set other frequencies just by typing them into Output 1 box and
clicking "Find" This will find and program the new frequency.
If you want two separate frequencies at the same time it gets a bit
tricky
and often need manual setup. In such case let me know what combination
you
would like and i will try to find the correct settings."
While this is process is helpful, it is hardly convenient and frankly me
deciphering the doc without a Rosetta Stone isn't going to happen.

==================================
Wes,
Yes, the second frequency does depend on the first, and this is noted in the
review:

You can easily have both outputs at the same frequency (e.g. 10 MHz),
though. Thanks for the pointer to the datasheet.
For me, just having the easily-adjustable single GPS-locked frequency in
such a compact, ready-to-run, unit is great. Perhaps someone will write a
little program to enable fuller use of the second output.
