Number of DQS Delay Buffer Stages
Table 5–98. DQS Phase-Shift Error Specifications for DLL-Delayed Clock (tDQS_PSERR)
This error specification is the absolute maximum and minimum error. For example, skew on three delay buffer
stages in a C3 speed grade is 75 ps or ± 37.5 ps
Delay stages used for requested DQS phase shift are reported in your project’s Compilation Report in the
Quartus II software.

(tDQS_CLOCK_SKEW_ADDER)
Number of DQS Delay
Peak-to-peak phase jitter on the phase shifted DDS clock (digital jitter is caused
by DLL tracking).
Delay stages used for requested DQS phase shift are reported in your project’s
Compilation Report in the Quartus II software.
This skew specification is the absolute maximum and minimum skew. For
example, skew on a ×4 DQ group is 40 ps or ±20 ps.
