A high speed serial interface is provided. In one aspect, the high speed serial interface uses three phase modulation for jointly encoding data and clock information. Accordingly, the need for de-skewing circuitry at the receiving end of the interface is eliminated, resulting in reduced link start-up time and improved link efficiency and power consumption. In one embodiment, the high speed serial interface uses fewer signal conductors than conventional systems having separate conductors for data and clock information. In another embodiment, the serial interface allows for data to be transmitted at any speed without the receiving end having prior knowledge of the transmission data rate. In another aspect, the high speed serial interface uses polarity encoded three phase modulation for jointly encoding data and clock information. This further increases the link capacity of the serial interface by allowing for more than one bit to be transmitted in any single baud interval.

A method and apparatus for enabling a local area network wiring structure to simultaneously carry digital data and analog telephone signals on the same transmission medium. It is particularly applicable to a network in star topology, in which remote data units (e.g. personal computers) are each connected to a hub through a cable comprising at least two pairs of conductors, providing a data communication path in each direction. Modules at each end of the cable provide a phantom path for telephony (voice band) signals between a telephone near the data set and a PBX, through both conductor pairs in a phantom circuit arrangement. All such communication paths function simultaneously and without mutual interference. The modules comprise simple and inexpensive passive circuit components.

The invention relates to a method and a device for transmission with reduced crosstalk in interconnections used for sending a plurality of signals, such as the interconnections made with flat multiconductor cables, or with the tracks of a printed circuit board, or inside an integrated circuit.

Provided are a current mode differential transmission method and system for differentially transmitting three units of data using four signal lines. The method includes: dividing the four signal lines 1a, 1b, 2a and 2b into two pairs of signal lines 1a / 1b and 2a / 2b, and differentially transmitting respective data (first data and second data) via the two pairs of signal lines 1a / 1b and 2a / 2b; and transmitting the other data (third data) by differentially changing common mode currents of the two pairs of signal lines 1a / 1b and 2a / 2b.

The intermediate node of the first terminator connected between a pair of signal lines transmitting the first differential signal with one side of the third differential signal as a common voltage and the intermediate node of the second terminator connected between a pair of signal lines transmitting the second differential signal with the other side of the third differential signal as a common voltage are connected by the intermediate connection. Thus, the intermediate node of the first terminator and the intermediate node of the second terminator act as a virtual ground of the third differential signal, enabling the matching of the impedance of the terminators related to the third differential signal and the impedance of the signal lines related to the third differential signal. It is thus able to prevent the reflection of the third differential signal.
