A fully integrated SiGe receiver IC for 10 Gb/s data rate

A silicon germanium (SiGe) receiver IC integrates most of the 10 Gb/s SONET receiver functions previously implemented using GaAs HBT components. The receiver combines an AGC, clock and data recovery circuit (CDR) with a binary type PLL, 1:8 demultiplexer, and a 2/sup 7/-1 PRBS generator for self-testing. Compared to other silicon designs, this work demonstrates a higher level of integration as well as a CDR with SONET-compliant jitter characteristics.
