Notes to Table 1–43
(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 applies to commercial, industrial, and military speed grades.
(4) This is the number of repetition for the stated training pattern to achieve 256 data transitions.
(5) Slow clock = Data rate (Mbps)/Deserialization factor.
