Note:
1. For dual-module macros, use tPD + tRD1 + tPDn, tRCO + tRD1 + tPDn, or tPD1 + tRD1 + tSUD, whichever is appropriate.
2. Routing delays are for typical designs across worst-case operating conditions. These parameters should be used for estimating
device performance. Post-route timing analysis or simulation is required to determine actual worst-case performance. Post-route
timing is based on actual routing delay measurements performed on the device prior to shipment.
3. Delays based on 35 pF loading, except tENZL and tENZH. For tENZL and tENZH the loading is 5 pF.
