摘要： One embodiment provides a network device that includes PHY circuitry comprising transmit circuitry (Tx) and receive circuitry (Rx), wherein the Tx and Rx circuitry are configured to be coupled to a respective channel to communicate with an external device via the channels, wherein the network device configured to communicate with the external device using an Ethernet communications protocol; and test circuitry. The test circuitry is configured to: designate a through channel and at least one crosstalk channel from among the channels; determine, in the time domain, an approximate available signal voltage of a first response signal, wherein the first response signal is in response to a test signal applied to the through channel; determine a first noise profile of the first response signal in response to the test signal applied on the through channel; determine a second noise profile of a second response signal, wherein the second response signal is in response to the test signal applied on a crosstalk channel and measured on the through channel; and determine a signal-to-noise ratio of the through channel based on, at least in part, the approximate available signal voltage and the first and second noise profiles.

摘要： Techniques are described that can extend the transmission rate over cable. Multiple cables can be used to increase the transmission rate. The transmission standard applied for each cable can be an Ethernet backplane standard such as IEEE 802.3ap (2007). Data can be assigned to virtual lanes prior to transmission over a cable. Forward error correction may be applied to each virtual lane prior to transmission over cable. Forward error correction may be negotiated over a single virtual lane and then applied to all virtual lanes.

摘要： Embodiments of the invention include a Printed Wiring Board (PWB) having a first via connected to a top-side signal source, a second via connected to a bottom-side signal destination, and a third via connected to the first via on a lower signal layer of the PWB and further connected to the second via on an upper signal layer of the PWB. In embodiments of the invention, the third via is referred to as an S-Turn via. The S-Turn PWB routing configuration advantageously reduces reflections causes by via stubs at Multi-Giga Hertz (MGH) frequencies. Other embodiments are described.
