Limits are guaranteed by 100% testing, sampling, or correlation with worst-case test conditions.
This does not include the current from the AUI pull-down resistors, or LED status outputs.
LED drivers can sink up to 20mA, but V
OL
will be higher.
Does not include pre-bias current for fiber optic LED which would typically be 3mA.
Threshold for switching from Link Fail to Link Pass (Low Light).
