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, Idd, and electrical AC and DC characteristics may be conducted
4. AC timing may use a Vil-to-Vih swing of up to 1.5V in the test environment, but input
5. Clock phase jitter is the variance from clock rising edge to the next expected clock ris-
6. Frequency drift is not allowed.
