Be aware they don't mean the same with "jitter" as you do: they
include production tolerances, so the 200ps is the worst case jitter
measured between two output pins on a large lot of chips, not the
jitter you would measure on a single output on a single chip.

Never attribute to malice what can adequately be explained by incompetence.
