Abstract
A gearbox IC is incorporated into an optical communications system to enable an optical link that incorporates the system to achieve data rates that are at least double that which are currently achievable in optical links. The gearbox IC performs data rate conversion and phase alignment. In the transmit direction, the gearbox IC receives N lanes of electrical data signals having a data rate of X Gbps and outputs N/2 lanes of electrical data signals having a data rate of 2X Gbps. In the receive direction, the gearbox IC receives N/2 electrical data signals having a data rate of 2X Gbps and converts the N/2 electrical data signals into N electrical data signals having a data rate of X.
