Notes:
1. AC parameters are guaranteed by design and characterization.
2. CL includes scope probe and test jig capacitance.
3. t
SKD1 is the magnitude difference of differential propagation delays in a channel. tSKD1 = |tPHLD - tPLHD|.
4. t
SKD2 is the magnitude difference of the tPLHD or tPHLD of one channel and the tPLHD or tPHLD of any other channel on the same device.
