That's a 1000
CPR encoder. It's 4000 PPR at 4X.
That's 4.4 microseconds per edge, assuming zero tolerance on symmetry and quadrature delay.
I could not find symmetry or quadrature delay specs in the S5 datasheet.
The S4 datasheet has max quadrature delay tolerance of 60 electrical degrees. I doubt the S5 is that bad (because the disk is assembled at the factory, not by the user), but just for comparison: with a quadrature delay tolerance of 60 electrical degrees, the microseconds per edge could be as fast as 1.5.
