The CURRENT_PH_DATA[15:0] bits represent a 2’s complement signed integer. If the value is multiplied by 0.61, the
averaged phase error of the T0/T4 DPLL feedback with respect to the selected input clock in ns will be gotten.

The DPLL_FREQ_HARD_LIMT[15:0] bits represent an unsigned integer. If the value is multiplied by 0.0014, the
DPLL hard limit for T0 and T4 paths in ppm will be gotten.
The DPLL hard limit is symmetrical about zero.
