Notes:

1. AC parameters are guaranteed by design and characterization.

2. CL includes scope probe and test jig capacitance.

3. tSKD1 is the magnitude difference of differential propagation delays in a channel. tSKD1 = |tPHLD - tPLHD|.

4. tSKD2 is the magnitude difference of the tPLHD or tPHLD of one channel and the tPLHD or tPHLD of any other chan-

nel on the same device.

5. tSKD3 is the magnitude difference of any differential propagation delays between devices operating over rated

conditions at the same VCC and within 5ºC of each other.

6. tSKD4 is the magnitude difference of any differential propagation delays between devices operating over rated

conditions.

7. fMAX generator output conditions:

a. Rise time = fall time = 1ns (0 to 100%)

b. 50% duty cycle

c. VOH = +1.3V

d. VOL = +1.1V

8. Output criteria:

a. Duty cycle = 60% to 40%

b. VOL = 0.4V (max)

c. VOH = 2.7V (min)

d. Load = 15pF
