NOTES:
1. These parameters are not production tested.
2. This is considered as static phase error.
3. Phase error does not include jitter. (tphase error = static phase error – jitter(cycle-cycle))
4. The tSK(0) specification is only valid for equal loading of all outputs.

NOTES:
1. CL includes probe and jig capacitance.
2. All input pulses are supplied by generators having the following characteristics: PRR ≤ 100MHz, ZO = 50Ω , tr ≤ 1.2ns, tf ≤ 1.2ns.
3. The outputs are measured one at a time with one transition per measurement.
