Notes:
17. The ratio of rise time to falling time must not vary by greater than 2:1.
18. For a given operating frequency, neither rise or fall specification can be greater than 20% of the clock-cycle period or the data sheet maximum time.
19. All transmit AC timing parameters measured with 1ns typical rise time and fall time.
20. Parallel data output specifications are only valid if all outputs are loaded with similar DC and AC loads.
21. Receiver UI (Unit Interval) is calculated as 1/(f
*20) (when TRGRATEA = 1) or 1/(f
TRG
* 10) (when TRGRATEA = 0). In an operating link this is equivalent to t
B
.
22. The duty cycle specification is a simultaneous condition with the t
REFH
and t
REFL
cycle cannot be as large as 30%–70%.
