摘要： Continuous-time linear equalization of received signals on multiple wire channels while maintaining accurate common mode signal values. Multiwire group signaling using vector signaling codes simultaneously transmits encoded values on multiple wires, requiring multiple receive signals to be sampled simultaneously to retrieve the full transmitted code word. By misaligning transitions on multiple wires, skew introduces a transient common mode signal component that is preserved by using frequency-selective common mode feedback at the receiver to obtain accurate sampling results.

摘要： Vector signaling codes are synergistically combined with multi-level signaling, the increased alphabet size provided by the multi-level signaling enabling a larger codeword space for a given number of symbols, at the cost of reduced receiver detection margin for each of the multiple signal levels. Vector signaling code construction methods are disclosed in which code construction and selection of multi-level signal levels are coordinated with the design of an associated receive comparator network, wherein modified signal levels encoded and emitted by the transmitter result in increased detection margin at the receive comparators.

摘要： Methods and systems are described for adjusting the sample timing of a data sampler operating in a data signal processing path having a decision threshold associated with a decision feedback equalization (DFE) correction factor. The vertical threshold and sample timing of a spare sampler are varied to measure a signal amplitude trajectory of a pattern-verified signal according to detection of the predetermined transitional data pattern, the locked sampling point then being adjusted based on the measured signal amplitude trajectory.

摘要： Methods are described for identifying and acting upon predetermined message patterns during reception of a data stream structured as USB message frames. A first embodiment performs pattern matching between received message bits and one or more predetermined sequences, identifying unscrambled ordered set messages. A second embodiment applies a descrambling operation and performs comparable pattern matching between descrambled received message bits and one or more additional predetermined sequences, identifying scrambled ordered set messages.

摘要： In a high-impedance communications interface, driver energy consumption is proportional to the number of signal transitions. For signals having three or more distinct levels, it is possible for a signal driver to salvage energy from some downward signal transitions and reuse it on some subsequent upward signal transitions. To facilitate this energy-conserving behavior, communication is performed using group signaling over sets of wires using a vector signaling code, with the design and use of the vector signaling code insuring that energy availability is balanced with energy demand.
