An efficient signaling scheme for serial-data transceivers (TRXs) has been proposed, which can properly reduce inter-symbol interference (ISI) and crosstalk (Xtalk) in memory interfaces. The proposed architecture relies on fully-digital implementation rather than analog/multi-tone approach, which can offer a very power-efficient and versatile silicon implementation. Moreover, the Xtalk induced noise can be fairly reduced by applying the proposed signaling, and the whole TRX can customize to the communication link trough digital calibration, while the aggregate data rate is kept fixed.
