(1) All timing parameters are described in Tables 32 through 38 in this data sheet.
(2) Using an LE to register the signal may provide a lower setup time.
(3) This parameter is specified by characterization.
(4) This parameter is measured without the use of the ClockLock or ClockBoost circuits.
(5) This parameter is measured with the use of the ClockLock or ClockBoost circuits.
