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