Abstract
An Ethernet transceiver integrated circuit (IC) chip is disclosed. The IC chip includes multiple physical sub-channels, where each sub-channel transfers data symbols along a wired link. Each data symbol representing a group of multiple data bits. Logic determines a signal quality parameter value for each of the sub-channels. For each sub-channel, in a first mode where a given sub-channel exhibits a signaling quality above a first predetermined threshold, the logic assigns a modulation of a first type associated with a first constellation. In a second mode where a given sub-channel exhibits a signaling quality below the first predetermined threshold, the logic assigns a modulation of a second type associated with a second constellation that is sparser than the first constellation. Where a second sub-channel exhibits a signaling quality above a third predetermined threshold that is higher than the first threshold, the logic assigns a modulation of a third type associated with a third constellation that is denser than the first constellation.
