1. All timing parameters are measured relative to the crossing point of CK/CK#, DK/DK#
2. Outputs measured with equivalent load:
3. Tests for AC timing, I
4. AC timing may use a V
5. Clock phase jitter is the variance from clock rising edge to the next expected clock ris-
6. Frequency drift is not allowed.
