Roland Best, "Phase Locked Loops". I see from Amazon that it is up the
6th edition. I think I have the 3rd edition.
https://www.amazon.com/Phase-Locked-Loops-Simulation-Applications/dp/0071493751/ref=sr_1_1?ie=UTF8&qid=1490121310&sr=8-1&keywords=best+phase+locked+loops
I took a PLL class at StorageTek a while back; an earlier revision of
this book was used and I found it to be a good text.

Have to say a search for PLL book by Best generates lots of stuff. None of
it about PLLs. Better hint please? I think Lyons may be a bit better.

I'm trying to understand how to design and analyze the loop filters in a
digital PLL. Specifically, because of digital processing delays, the
phase
offset measured at time t will only produce a change on the VCXO input at
time t+T, where T is the sampling period of the digital loop.
You have the same delays in analog filters as well. As a rule of thumb
you can assume that the delays are in the same order of magnitude as
with the equivalent analog filters, not accounting for the delays due to
pre- and post-processing of the signal.
The analysis of digital PLLs works the same as with analog ones, you
just exchange the Laplace transform with the Z-transform. You can add
arbitrary delays due to pre/post-processing as a simple multiplication
by 1/z for each clock cycle of delay.
I've found plenty of texts describing analog loop filters. Are there any
recommendations for digital loop filter PLL design?
The PLL book by Best contains two chapters on how to design digital PLLs.
I can also recommend "Understanding digital signal processing" by Lyons,
which is a very hands-on description how to do filters and perform other
signal processing tasks.
