Into 1M of 50Ω transmission line terminated with 1KΩ and 5 pF with the proper series termination
resistor.
LOW LEVEL = 0V, HIGH LEVEL = 3.3V.
Measured at 2.5V with VH = +5V, VL = 0V.
Guaranteed by design and characterization. This parameter is not tested in production.
Tested with a 30 mA load.
Guaranteed by characterization. (This parameter is tested in production against 40 MHz limits.)
