摘要： A physical layer device comprises a transmitter of a first network device that transmits an autonegotiation signal to a second network device. A receiver of the first network device receives a received signal from the second network device. An autonegotiation controller autonegotiates link parameters for a link between the first network device and the second network device, monitors autonegotiation pulses in the autonegotiation signal relative to autonegotiation pulses in the received signal received during a window, and selectively blinds autonegotiation based on the monitoring.

摘要： A physical layer (PHY) device includes a first encoder that receives a first data stream at a first data rate, that encodes the first data stream using a first type of encoding, and that outputs first encoded data. A second encoder receives a second data stream at a second data rate different than the first data rate, encodes the second data stream using a second type of encoding different than the first type of encoding, and outputs second encoded data. An output selector outputs the first encoded data to a serializer of the PHY when the PHY transmits at the first data rate, and outputs the second encoded data to the serializer when the PHY transmits at the second data rate.

摘要： A transmit path in a physical layer device comprises a first transmit encoding device that has N outputs, that receives a first data stream at a first data rate and that performs a first type of encoding on the first data stream. A second transmit encoding device has an output, receives a second data stream at a second data rate and performs a second type of encoding on the second data stream. The first data rate is N times the second data rate. An output selector has a first set of N inputs that communicates with the N outputs of the first transmit encoding device, a second set of N inputs that communicate with the output of the second transmit encoding device and N outputs. The output selector selectively connects one of the first and second sets of N inputs to the N outputs.

摘要： A transmitter within a line driver circuit is configured to supply data signals in compliance with the Multilevel Transmission-3 (MLT-3) protocol for high speed data communication. The transmitter comprises a pre-driver system and a final driver. The pre-driver system comprises a plurality of individual pre-drivers that are in parallel. A zero drive logic designates any number of individual pre-drivers as zero drive types, such that these designated zero drive pre-drivers are turned ON during a zero signaling state. The partially turned ON pre-driver system, during the zero state, permits the final driver to rapidly output positive and negative signals in accord with the MLT-3 protocol.

摘要： An optimum equalizer setting is determined for a signal equalizer in a network receiver by successively setting the equalizer to different predetermined settings, detecting timing correlation results between the equalized signal and a recovered clock in a digital phase locked loop, and determining a normalized distribution result for each of the predetermined equalizer settings based on the timing correlation results. The equalizer setting having the minimum normalized distribution result can then be selected as the optimum equalizer setting. Use of the correlation result from the phase locked loop enables the equalizer controller determining the optimum equalizer setting to determine the setting using a closed-loop setting. Hence, the equalizer controller can effectively determine the equalizer setting that causes the minimum amount of jitter in the phase locked loop.
