  • Patent number: 7032058
    Abstract: Bus communications are optimized by adjusting signal characteristics in accordance with one or more topography dependent parameters. In a bus transmitter, a transmit signal characteristic is adjusted in accordance with a topography dependent parameter. A port in the bus transmitter receives the topography dependent parameter for later use by the parameter adjustment circuitry. The parameter adjustment circuitry adjusts a parameter control signal in accordance with the topography dependent parameter, which is coupled to the output driver. Prior to driving an output signal onto a bus, the output driver adjusts the transmit signal characteristic in accordance with the parameter control signal. Similarly, in a bus receiver, a receive signal characteristic is adjusted in response to a topography dependent parameter.

  • Publication number: 20050135182
    Abstract: A chip-to-chip communication system and interface technique. A master and at least two devices are interconnected with a signal line of a high speed bus. A capacitive coupling element, for example a diode, is employed to capacitively couple the interface of the device to the signal line. By employing the capacitive coupling element, along with a suitable signaling technique which supports capacitive information transfer, high speed rates of information transfer between the master and device over the signal line are achieved.

  • Patent number: 5663661
    Abstract: A modular bus permitting single or double termination is described. The bus includes a terminated motherboard data net for communicating data signals between a master and one or more motherboard devices. A socket is used for coupling the data signals between the motherboard data net and a terminated module data net of a removable module. The module data net communicates the data signals between the master and one or more module devices. The data signal swing and level of reflection of the data signals are substantially independent of the presence of the module.
