15. Jitter on X1 input must be less than ± 0.2 ns to ensure that automatic test equipment can properly measure device
16. This specification is the sum of Data Dependent Jitter, Duty Cycle Distortion, and Random Jitter.
18. ACK delay is determined by t 13 when the input latch is empty or by t 15 when the latch is full (Busy mode). Also note that ACK

20. All timing references are made with respect to +1.5 V for TTL–level signals or to the 50% point between V
21. Device thresholds on the SERIN ( +/– ) pin(s) are verified during production test by ensuring that the input threshold is less
22. Switching Characteristics are tested during 8-bit local mode operation.
23. The limit for this parameter cannot be derived from t 37 and t 42 .
24. This specification does not apply during reacquisition when CLK stretch can occur.
