  • Patent number: 8922298
    Abstract: A cable emulator configured to emulate the electrical transfer function and properties of a length of conductive cable is disclosed for use in transmitter, receiver and transceiver operation without need for long and expensive length of actual cable. The cable emulator includes an input port for connection to a signal source, such as a transmitter and an output port for connection to a receiver or other signal analyzer. The input port connects to an input impedance matching element, which in turn connects to one or more filter stages. The output of the one or more filter stages connects to an output impedance matching element, which then connects to the output port. The one or more filter stage comprises one or more resistors, one or more inductors and one or more capacitors.

  • Patent number: 7130944
    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: 7051129
    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.
