New 2 Gbit/s CMOS I/O pads

A couple of low complexity high performance input and output pads are proposed: they have been designed in 0.7 /spl mu/m CMOS ES2 technology and support bit rates ranging from DC up to 2 Gbit/s. The differential input pad and the differential output pad interface true PECL external logic levels to full swing 5 V CMOS internal levels.
