1:4 DEMUX IC in SiGe Technology

3 now with BigBear Networks, Sunnyvale, CA To meet the rapidly increasing demands of internet traffic, today's fiber-optic time-division multiplexing systems (TDM) are moving from 10Gb/s to 40Gb/s data rates. In a fiber-optic com- munication system, the CDR is a key electronic component. The design of the 40Gb/s CDR for commercial use is challenging, since robustness in architecture and production technology is
