    摘要: Signaling and coding methods and apparatus for long-range 10 and 100 mbps Ethernet transmission. In accordance with the method, a physical layer (PHY) device is provided that includes the long-range capabilities. In operation, the PHY measures the distance to a companion PHY, and if it is within the specification limits, communicates with the companion device in the normal way. If the distance is above the specification limits, the PHY checks to see if the companion PHY is similarly enabled, and if so, switches to a long-range signaling method. In a preferred embodiment, NRZ coding with pre-emphasis on the first bit of two or more bits of the same value is used for a first range exceeding the specification limit, and PAM4 coding is used for a second range exceeding the first range. Various embodiments are disclosed.

    摘要: The invention disclosed a data transmission system, comprising a first conversion module provided on the host side, used for converting USB data into data in format which may be transmitted by a data transmission module and for converting data in format which may be transmitted by the data transmission module into USB data the data transmission module provided between the host and the monitor, used for data intercommunication between the host and the monitor, and a second conversion module provided on the monitor side, used for converting USB data into data in format which may be transmitted by the data transmission module and for converting data in format which may be transmitted by the data transmission module into USB data. Wherein, the data transmission module is a DisplayPort auxiliary channel (DisplayPort AUX CH). With the invention, the connection of the personal computer host and the monitor may be realized by using only one DisplayPort cable, thereby USB interfaces may be integrated on the monitor. The manner may reduce the complexity and cost of the computer system, and may enhance the user experience.
