A Digital Spectrum Shaping Signaling Serial-Data Transceiver With Crosstalk and ISI Reduction Property in Multidrop Interfaces

A transceiver (TRX) architecture employing a spectrum shaping signaling scheme is proposed, which can significantly reduce intersymbol interference and crosstalk in multidrop interfaces. The proposed TRX architecture relies on digital implementation rather than an analog/multitone approach, which can offer a power-efficient and versatile silicon implementation. Moreover, the crosstalk-induced noise can be reduced by applying the spectrum shaping signaling, and the whole TRX can be customized to the communication link by digital calibration while the aggregate data rate is kept fixed.
