NOTE:
1.Time required for the integrated PLL circuit to obtain phase lock of its feedback signal to its reference signal. For phase lock to be obtained, a fixed-frequency, fixed-phase reference
signal must be present at CLK. Until phase lock is obtained, the specifications for propagation delay, skew, and jitter parameters given in the switching characteristics table are
not applicable.

NOTES:
1. All parameters are measured with the following load conditions: 30pF || 500Ω for 3.3V outputs and 20pF || 500Ω for 2.5V outputs.
2. The specifications for parameters in this table are applicable only after any appropriate stabilization time has elapsed.
3. Phase error does not include jitter.
4. All skew parameters are only valid for equal loading of all outputs.
5. Measured for VDDQ = 2.3V and 3V, 2.5V and 3.3V, or 2.7V and 3.6V.
