A 22Gb/s, 10mm on-chip serial link over lossy transmission line with resistive termination

An on-chip serial-link scheme incorporating an interleaved voltage-mode driver, interleaved samplers and an optimally resistively terminated transmission line, enables an energy-efficient very-high-speed long-range data communication. The link is more than twice as fast and more than twice as energy efficient as the fastest reported on-chip link, yet has more than triple the communication range. A 10mm prototype link achieves a data rate of 20Gb/s with an energy consumption of 1.36pJ/b and a measured BER better than 10^-11. A 10Gb/s prototype achieves an energy efficiency of 680fJ/b with a measured BER of less than 10^-13.
