摘要： An efficient communications apparatus is described for a vector signaling code to transport data and optionally a clocking signal between integrated circuit devices. Methods of designing such apparatus and their associated codes based on a new metric herein called the “ISI Ratio” are described which permit higher communications speed, lower system power consumption, and reduced implementation complexity.

摘要： An integrated circuit includes a plurality of signal inputs, a receiver, calibration circuitry, and input switch circuitry. The receiver includes differential input terminals. The calibration circuitry is configured to calibrate an input offset between the differential input terminals of the receiver in response to the integrated circuit being placed in a calibration mode. The input switch circuitry is configured to switch electrical connections between the plurality of signal inputs and the differential input terminals of the receiver in response to the integrated circuit being placed in a mode different from the calibration mode. The input switch circuitry is further configured to electrically disconnect the plurality of signal inputs from the differential input terminals of the receiver in response to the integrated circuit being placed in the calibration mode.

摘要： Assemblies, apparatus, devices and methods useful in providing lightning protection of avionic components associated with aircraft antennas are disclosed. Aspects of the present disclosure may be used on aircraft comprising structural elements made from composite materials having a relatively low electrical conductivity. An exemplary assembly disclosed comprises: an antenna secured to a structural element of the aircraft and configured to receive wireless signals and/or transmit wireless signals external to the aircraft; a communication unit operatively connected to the antenna for signal transmission between the antenna and the communication unit; and an isolation transformer electrically disposed between the antenna and the communication unit where signal transmission between the antenna and the communication unit is conducted via the isolation transformer.

摘要： Described examples include an integrated circuit including a receive portion to receive an encoded transmission on a line. The receive portion has: a wake mode in which the receiver is capable of receiving the encoded transmission; and a sleep mode in which the receiver is not capable of receiving the encoded transmission. A wakeup controller monitors the line for a wakeup signal and provides a signal to the receive portion to cause the receive portion to enter the wake mode when the wakeup controller receives the wakeup signal.

摘要： Methods and systems for rapidly recovering from a serious interference. One method includes the following steps: transmitting, by a transmitter to a transceiver over a communication channel, ongoing data at a fixed data rate above 100 Mbps; receiving, by a receiver from the transceiver, an indication indicating that the transceiver is experiencing a serious interference; responsive to the indication, reducing data rate at which the transmitter transmits; storing excess data that cannot be sent during the period of the reduced data rate; and increasing the data rate, at which the transmitter transmits, to a level that enables it to transmit, within less than 1 millisecond from the moment of reducing the data rate, both the stored excess data and the ongoing data at the fixed data rate.

摘要： An auxiliary channel transceiving circuit includes: a first node and a second node; a first voltage-dividing circuit for generating a first received signal according to a signal from the first node; a second voltage-dividing circuit for generating a second received signal according to a signal from the second node; a first receiver amplifying circuit for amplifying the first received signal to generate a first amplified signal; a second receiver amplifying circuit for amplifying the second received signal to generate a second amplified signal; a comparison circuit for comparing the first amplified signal with the second amplified signal to generate a received signal; a first transmitter amplifying circuit for generating a first output signal according to a transmitting signal; and a second transmitter amplifying circuit for generating a second output signal according to the transmitting signal. The auxiliary channel transceiving circuit is not required to cooperate with traditional capacitors.

摘要： Embodiments herein include a replica communication path and monitor circuit to provide increased common mode transient immunity. As its name suggests, the monitor circuit monitors the replica communication path and produces an adjustment signal (common mode transient adjustment signal) to cancel presence of a common mode transient signal in one or more other communication paths conveying data signals.
