Table 1–44 lists the DPA lock time specifications for Stratix IV GX and GT devices.
Figure 1–5 shows the LVDS soft-CDR/DPA sinusoidal jitter tolerance specification for
a data rate equal to or higher than 1.25 Gbps. Table 1–45 lists this information in table
form.

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.
