eX Timing Model
Hardwired Clock
External Setup = tINYH + tIRD1 + tSUD – tHCKH
= 0.7 + 0.3 + 0.5 – 1.1 = 0.4 ns
Clock-to-Out (Pad-to-Pad), typical
= tHCKH + tRCO + tRD1 + tDHL
= 1.1 + 0.6 + 0.3 + 2.6 = 4.6 ns
Routed Clock
External Setup = tINYH + tIRD2 + tSUD – tRCKH
= 0.7 + 0.4 + 0.5 – 1.3= 0.3 ns
Clock-to-Out (Pad-to-Pad), typical
= tRCKH + tRCO + tRD1 + tDHL
= 1.3+ 0.6 + 0.3 + 2.6 = 4.8 ns
Note: Values shown for eX128–P, worst-case commercial conditions (5.0 V, 35 pF Pad Load).
