≤ 6 ns (10% to 90%).
(2) See TIA/EIA-422-B specifications for exact test conditions.
(3) Devices are at the same V

and within 5°C within the operating temperature range.
(4) All channels switching, output duty cycle criteria is 40%/60% measured at 50%. This parameter is ensured by design and
characterization.
