Clocking and circuit design for a parallel I/O on a first-generation CELL processor

A parallel I/O is integrated on a first-generation CELL processor in 90nm SOI CMOS. A clock-tracking architecture suppresses reference jitter to achieve 6.4Gbit/s/link operation at 21.6mW/Gbit/s. SOI effects on analog circuits, in particular high-speed receivers, are addressed to achieve a receiver sensitivity of /spl plusmn/12mV at 6.4Gbit/s with BER <10/sup -14/ measured using 7b PRBS data.
