A 10 Gb/s CMU in SiGe BiCMOS commercial technology with multistandard capability

摘要

A 10 Gb/s CMU has been fabricated in a commercial SiGe BiCMOS technology featuring multistandard compliance with SDH/SONET and 10 GbE specifications,dual reference clock frequency and output jitter below 80 mUIpp.The phase tracking loop uses a charge pump with low common mode current to minimize frequency ripple.Power supply is 2.5 and 3.3 V and the total power consumption is below 480 mW.
