Mixed signals technology-dedicated to demonstrating and evaluating high-speed serial links using optical, wired or wireless channels-provides GEC member companies and Georgia Tech with exposure in the area of high data-rate wireless, wired nad optical applications.

The primary research goal for this testbed is to explore, develop and demonstrate innovative solutions that enable signal integrity for wireless, wired and optical communication systems.

Particular emphasis is given to developing and evaluating silicon ICs that can compensate for static and stochastic channel impairments such as band limitation, dispersion and mode-partition noise. As a result, these silicon ICs extend the data reach distance and/or improve the bit-error rate (BER), enabling data communication beyond its original design specifications.

Within the unified 10Gbit/s physical layer initiative, Mixed signal technology is involved in researching and developing short reach (chip-to-chip) and long reach (backplane) electrical interconnects between 9.95 and 11.1 Gbit/s.
