Chris Moscone, Qazi Omar Farooq Cadence, Cary, NC With recent AI and big data developments, quickly moving massive amounts of data is paramount to future technologies. Scalable solutions that can sustain higher performance systems that consume ever-increasing amounts of data are necessary. Low power, low latency, and aggregation are essential in highly scalable data-distribution solutions [2]. A new metric of bandwidth density is rising in importance as physical limits are being encountered [1]. This design improves bandwidth density through single-ended signaling that employs a spatial 6/7b encoding scheme to emulate a fully differential signaling scheme. Although differential signaling schemes provide better signal integrity, they typically cost more in terms of power and die area. Regardless of the signaling scheme utilized, power distribution and channel constraints must be managed to achieve
