Volume 4: Device Datasheet and Addendum
Table 1–45 lists the LVDS soft-CDR/DPA sinusoidal jitter tolerance specification for a
data rate equal to or higher than 1.25 Gbps.
Figure 1–6 shows the LVDS soft-CDR/DPA sinusoidal jitter tolerance specification for
a data rate less than 1.25 Gbps.
When the data rate is equals to 800 Mbps, the LVDS soft-CDR/DPA sinusoidal jitter
tolerance allows up to 0.1 UI (125 ps) for jitter frequencies between 479.9 kHz and
20 MHz.
