Notes:
1. The –2 and –3 speed grades have been discontinued. Refer to PDN 0104, PDN 0203, PDN 0604, and PDN 1004 at
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.
