A 40/43-Gb/s CDR/DEMUX and MUX chipset integrated on a MCM-ceramic with 3R-regeneration functionality

A second-generation 40/43-Gb/s CDR/DEMUX and MUX chipset in a 120-GHz-f/sub T/ SiGe technology is presented. While consuming 3.4-W, the fully-integrated CDR/DEMUX provides an electrical sensitivity of less than 40-mVpp at a BER of 10/sup -12/, the MUX consumes 2.3-W. Additionally, the integration of the chipset as a 3R-regenerator on a ceramic is demonstrated.
