Definitions:
C_L= Load capacitance; Includes jig and probe capacitance.
R_T=Termination resistance; Should be equal to Z_OUT of the
Pulse Generator.
Note:
1. Pulse Generator: Rate ≤ 1.0 MHz, tF ≤ 2.5 ns, tR ≤ 2.5 ns.
2. AC tests are done with a single bit switching, and
timings need to be derated when multiple outputs are
switching in the same direction simultaneously. This derating
should not exceed 0.5 ns for 16 inputs switching
simultaneously.
