Notes to Table 1–47:
(1) The valid settings for phase offset are -64 to +63 for frequency modes 0 to 3 and -32 to +31 for frequency modes
4 to 6.
(2) The typical value equals the average of the minimum and maximum values.
(3) The delay settings are linear, with a cumulative delay variation of 40 ps for all speed grades. For example, when
using a –2 speed grade and applying a 10 phase offset settings to a 90° phase shift at 400 MHz, the expected
average cumulative delay is [625 ps + (10 × 10.5 ps) ± 20 ps] = 730 ps ± 20 ps.

buffers in a –2/–2x speed grade is ± 78 ps or ± 39 ps.
