The delay settings are linear.
The valid settings for phase offset are -64 to +63 for frequency mode 0 and -32 to
+31 for frequency modes 1, 2, and 3.
The typical value equals the average of the minimum and maximum values.
The worst-case half period is equal to the ideal half period subtracted by the DCD
and half-period jitter values.
The half-period jitter was characterized using a PLL driving DDIO outputs.
