AC Timing Test Conditions
All specifications are valid only if the mandatory isolation is employed and all differential signals are taken to be at AUI
side of the transformer.

Capacitance
Derating Factor
Output timing are measured with a purely capacitive load for 50pF. The following correction factor can be used for other
loads: C L 50pF+0.3ns/pF
Note: In the above diagram, the TX+ and TX- signals are taken from the AUI side of the isolation (transformer).
