Bit Name
These two bits define the Data Slicer threshold.
= 00: The Data Slicer generates a mark if the voltage on the RTIPn/RRINGn pins exceeds 40% of the peak amplitude.
= 01: The Data Slicer generates a mark if the voltage on the RTIPn/RRINGn pins exceeds 50% of the peak amplitude.
= 10: The Data Slicer generates a mark if the voltage on the RTIPn/RRINGn pins exceeds 60% of the peak amplitude.
= 11: The Data Slicer generates a mark if the voltage on the RTIPn/RRINGn pins exceeds 70% of the peak amplitude.
These two bits select the observation period, during which the peak value of the incoming signals is measured.
= 00: The observation period is 32 bits.
= 01: The observation period is 64 bits.
= 10: The observation period is 128 bits.
= 11: The observation period is 256 bits.
These two bits select the Monitor Gain.
= 00: The Monitor Gain is 0 dB.
= 01: The Monitor Gain is 22 dB.
= 10: Reserved.
= 11: Reserved.
