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 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.
