Output Delay Measurements
Output delays are measured using a Tektronix P6245
TDS500/600 probe (< 1 pF) across approximately 4” of FR4
microstrip trace. Standard termination was used for all
testing. The propagation delay of the 4” trace is
characterized separately and subtracted from the final
measurement, and is therefore not included in the
generalized test setups shown in
