The default value represents near lower limit for all reference frequencies, which is -9.913ppm (Stratum 3 compliant
value), regardless of the reference frequency.
The name ’lower’ is based on frequency.
The default value represents far lower limit for all reference frequencies, which is -11.287ppm (Stratum 3 compliant
value), regardless of the reference frequency.
The name ’lower’ is based on frequency.

Multiple-Period Far Lower Limit Bits: Total binary value of these bits and the
MPFLLRU register bits defines the far lower limit for the multiple period count of any
reference input, minus 1. The unit of the binary value is measured in 100 MHz clock
periods.
Multiple-Period Near Lower Limit Bits: Total binary value of these bits and the
MPNLLRL register bits defines the near lower limit for the multiple period count of
any reference input, minus 1. The unit of the binary value is measured in 100 MHz
clock periods.
