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

Multiple-Period Near Lower Limit Bits: Total binary value of these bits and the
MPNLLRU 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.
Multiple-Period Far Upper Limit Bits: Total binary value of these bits and the
MPFULRL register bits defines the far upper 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.
