Notes:
All timing parameters are measured at 1.5 V with 50 pF loading on CLKOUTA, unless otherwise noted. All output test conditions
are with C_L =50 pF. For switching tests, V_IL=0.45 V and V_IH =2.4 V, except at X1 where V_IH =V_CC – 0.5 V.
a This timing must be met to guarantee recognition at the next clock.
