22. REFCLK has no phase or frequency relationship with RXCLK and only acts as a centering reference to reduce clock synchronization time. REFCLK must be
23. The PECL switching threshold is the midpoint between the PECL− V
24. Static alignment is a measure of the alignment of the Receiver sampling point to the center of a bit. Static alignment is measured by the absolute difference of
25. Receiver UI (Unit Interval) is calculated as 1/(f
26. Error Free Window is a measure of the time window between bit centers where a transition may occur without causing a bit sampling error. EFW is measured
27. The specification is sum of 25% Duty Cycle Distortion (DCD), 10% Data Dependant Jitter (DDJ), 15% Random Jitter (RJ).
28. Parallel data output specifications are only valid if all outputs are loaded with similar DC and AC loads.
