(1) The minimum frequencies on CLKOUT and CLKOUTX2 are assuming M2 = 1.
For M2 > 1, the minimum frequency on these clocks will further scale down by factor of M2.
(2) The maximum frequencies on CLKOUT and CLKOUTX2 are assuming M2 = 1.
(3) The minimum frequency on CLKOUTHIF is assuming M3 = 1. For M3 > 1, the minimum frequency on this clock will further scale down
by factor of M3.
(4) The maximum frequency on CLKOUTHIF is assuming M3 = 1.
(5) Relock time assumes typical operating conditions, 10°C maximum temperature drift.
(6) Bypass mode: f_CLKOUT = F_INP if ulowclken = 0. For more information, see the Device TRM.
