The authors demonstrate an 8 Gbit/s CMOS link interface designed for u
se with parallel fibre-optic interconnect technology. The link interfa
ce is implemented in 0.8 mu m CMOS and consists of eight data channels
and one frame control channel each operating at 1 Gbit/s along with a
full-speed 1 GHz clock channel. The chip also provides dual-ported FI
FO buffers for interface to a host computer.
