Abstract :
A 9.95-11.3-Gb/s transceiver in 0.13-mum CMOS for XFP modules is presented. The CDR uses a dual-loop DLL/PLL with a binary phase detector to exceed XFP jitter specifications. The dual loop solves the problem of having a controlled jitter transfer bandwidth with a binary phase detector. A half rate binary phase detector with a 2:1 serializer implements full-rate I/O. Dispersion jitter from 12´´ of FR4 is equalized resulting in system JGEN under 4 mUIRMS and 35 mUI PP. Power consumption is 800 mW
