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.

operations are tested for the full voltage range specified.
timing is still referenced to Vref (or to the crossing point for CK/CK#), and parameter
specifications are tested for the specified AC input levels under normal use condi-
tions. The minimum slew rate for the input signals used to test the device is 2 V/ns in
the range between Vil(AC) and Vih(AC).
