Notes to Table 1–44:
(1) The DPA lock time is for one channel.
(2) One data transition is defined as a 0-to-1 or 1-to-0 transition.
(3) The DPA lock time stated in the table applies to commercial, industrial, and military speed grades.
(4) This is the number of repetitions for the stated training pattern to achieve the 256 data transitions.
