摘要： Embodiments of a clock and data recovery method and apparatus include receiving a multi-channel serial digitally encoded signal and converting the received signal to digital data, or set of binary characters. One embodiment includes determining whether a phase of a sampling circuit is appropriate to sample meaningful data from a received signal; if the phase of the sampling circuit is not appropriate, the phase is shifted so that sampling occurs earlier or later for the received signal. The determination is based, in one embodiment, on the order and value of the samples taken, which indicate whether the samples are taken too close to a transition of the received signal.

摘要： A system and method for multiple-phase clock generation is disclosed. In one embodiment, a multiple-stage voltage controlled oscillator (“VCO”) transmits a plurality of clock phases to a clock divider circuit which produces the desired number of clock phase outputs. The clock divider circuit in this embodiment includes a state machine, e.g., a modified Johnson counter, that provides a plurality of divided down clock phases, each of which is connected to a separate modified shift register. Each modified shift register contains D-type flip-flops and each D-type flip-flop provides a separate clock phase output. In one embodiment the number of clock phase outputs of the multiple-phase clock is a function of the number of VCO clock phases times the number of desired states in the modified Johnson counter.

The cable can include conductors, a memory storing cable data, and circuitry configured to respond to a request received on at least one of the conductors by accessing at least some of the cable data and asserting the accessed data serially to at least one of the conductors (e.g., for transmission to an external device).

The cable data can be indicative of all or some of cable type, grade, speed, length, and impedance, a date code, a frequency-dependent attenuation table, far-end crosstalk and EMI-related coefficients, common mode radiation, intra pair skew, and other information. The cable can include a radiation-emitting element and circuitry for generating driving signals for causing the radiation-emitting element to produce an appropriate color, brightness, and/or blinking pattern.

摘要： In preferred embodiments, an adaptive equalization circuit including at least two equalization filters (each for equalizing a signal transmitted over a multi-channel serial link) and control circuitry for generating an equalization control signal for use by all the filters. The control circuitry generates the control signal in response to an equalized signal produced by one of the filters, and asserts the control signal to all the filters. Preferably, one filter generates an equalized fixed pattern signal in response to a fixed pattern signal (e.g., a clock signal), each other filter equalizes a data signal, and the control circuitry generates the control signal in response to the equalized fixed pattern signal. In other embodiments, the invention is an adaptive equalization circuit including an equalization filter and circuitry for generating a control signal for the filter in response to a signal indicative of a predetermined fixed pattern, a receiver including an adaptive equalization circuit, a system including such a receiver, and a method for adaptive equalization of signals received over a multi-channel serial link.

Each bus line is used for carrying both clock and data information at different times.
