When using programmable modulus mode, is the tuning resolution listed the same
no matter what sample frequency I use?

 

No.  The absolute resolution is calculated as FSAM/2^64, though even that
doesn’t fully express it,  because with Programmable Modulus, you can actually
get values which fall between the discrete numbers that come from using 2^64 as
a non-variable in this equation.
