High Speed Interconnects



We are studying the use of novel coding techniques as well as hybrid opto-electronic systems for high speed interconnect. One technique we have investigated is to use a unique coding andtransceiver design for multi-bit differential signaling in both the optical and electronic domains. In this work, we expand on the idea of binary differential signals to using an equal weight (ones and zeros) coding scheme for multi-bit signals.
