Abstract :
Two chips communicate over a capacitively-coupled I/O link at 1.8Gb/s/ch. Channels are placed on a 36mum pitch. 144 channels operate simultaneously for an aggregate bandwidth of 260Gb/s, or 430Gb/s/mm2 in 0.18mum CMOS. Measured energy consumption is 3.0pJ/b and BER is <10-15. Electronic alignment and crosstalk rejection allow reliable I/O for practical implementation
