Notes:
All timing parameters are measured at V_CC/2 with 50 pF loading on CLKOUTA, unless otherwise noted. All
output test conditions are with C_L=50 pF. For switching tests, V_IL=0.3 V and V_IH =V_CC–0.3 V.
a This timing must be met to guarantee proper operation.
T _{b This timing must be met to guarantee recognition at the clock edge.}
