摘要： A skew adjustor that can reduce inter-pair skew between differential signals received via a cable is disclosed. In one embodiment, a skew adjustor includes: a skew detector that receives signals from a cable, and provides a detected skew amount when skew is detected between two of the signals; an offset controller for receiving the detected skew amount, and for providing a delay control signal in response thereto; and a skew delay circuit that receives the signals and the delay control signal, and enables one or more delay stages in a path of a first arriving of the two skewed signals based on the delay control signal, such that an adjusted skew between the two skewed signals at an output of the skew delay circuit is less than the detected skew amount by an amount corresponding to the enabled one or more delay stages.

摘要： An optical communications system and method at least doubles the data rate of the optical fiber link without requiring a redesign of the backplane ASIC. This is made possible in part through the incorporation of at least one gearbox integrated circuit (IC) is incorporated into the system that is compatible with the current ASIC design. The gearbox IC receives N lanes of electrical data signals from the ASIC, with each electrical data signal having a data rate of X Gbps, and outputs N/2 lanes of electrical data signals, with each electrical data signal having a data rate of 2X Gbps. The high-speed optical transceiver module receives the N/2 electrical data signals output from the gearbox IC and produces N/2 respective optical data signals having a data rate of 2X Gbps for transmission over the optical fiber link.

摘要： 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.

摘要： A power extractor suitable for locations proximate to the sink of a signal channel is disclosed. The power extractor can generate power from the signal channel without substantially disturbing a quality of signals within the channel. In one embodiment, the power extraction circuit can include: a current source coupled to a sink side of a signal channel, where the signal channel is independent of any power supply signal, the current source being high impedance to maintain signal quality within the signal channel; a first regulator configured to generate a first regulated supply from a current derived from the signal channel using the current source; and a second regulator coupled to the first regulator, where the second regulator is configured to generate a second regulated supply from the first regulated supply.
