computing and artificial intelligence applications pushes wireline transceivers to higher data rates. DSP-based transmitters (TX) and receivers (RX) have achieved 224Gb/s [1-2], but unfortunately consume substantial power. Furthermore, 224Gb/s SerDes places more stringent demands on the signal integrity of the passive components, such as connectors, channels, and packages. In contrast, the single-ended scheme may be a practical and cost-effective solution for 224Gb/s data rates. First, it doubles the throughput density by delivering two single-ended signals over one differential channel. Furthermore, this scheme relaxes the Nyquist bandwidth for the passive components. Unfortunately, single-ended links exhibit severe crosstalk,
