A high speed data cable carries high-speed and auxiliary signals, and includes a raw cable. The raw cable includes coaxial lines which are covered by an outer conductive shield. High-speed signals are carried on the inner conductors of a pair of coaxial lines. Lower speed signals are carried on the galvanically or capacitively coupled shields of a pair of coaxial lines, and/or the outer conductive shield.

High speed data cable using an outer braid to carry a signal

A high speed video cable carries signals according to the High-Definition Multimedia Interface (HDMI) or DisplayPort standards, and includes a raw cable and a boost device. The raw cable is exclusively constructed with either Shielded Twisted Pairs (STP) or coaxial lines which carry all signals on either shielded wires or their shields. The high speed signals are carried on the shielded wires to the boost device where any common mode noise induced by the signals on the shields is removed. Some auxiliary signals including power are carried on ungrounded shields.

Reduced wire count high speed data cable

A high speed video cable carries signals according to the High-Definition Multimedia Interface (HDMI) or DisplayPort standards, and includes a raw cable and a boost device. The raw cable includes coaxial lines of a characteristic cable impedance lower than the impedance implied in the standards. The correct impedance is observed at the sending end by series resistors mounted in the first cable connector. The resultant loss of signal is made up with the boost device mounted in the connector at the other end of the cable.

Low impedance boosted high speed data cable

A high-definition multimedia interface (HDMI) receiver recovers high speed encoded data which are transmitted differentially over data channels of a lossy cable, along with a clock. Inter symbol interference, high-frequency loss, skew between the clock and data channels, and differential skew within a differential signal are compensated by analog circuits which are automatically tuned for best performance by observing the quality of the recovered analog signal. Oversampling is used to provide a 24-bit digital representation of the analog signal for determining the quality of the signal.

Data recovery system for source synchronous data channels

A self calibrating cable, including a USB3 cable, with a boost device of the embodiment of the invention is described, in which parameters that control the response of the boost device are set optimally in a self-calibrating process comprising looping the boosted cable on itself through a calibration fixture that contains a calibration control device. The boost device includes pattern generators and a sampling circuit. Each high speed channel of the cable is separately tested and calibrated with the help of one of the other channels serving as a sampling channel. Additional embodiments provide for a selected replica boost device and a distinct pattern generator device in the calibration fixture. A corresponding system and method for calibrating a cable are also provided.

Boosted cable for carrying high speed channels and methods for calibrating the same

An HDMI cable carries high speed encoded data which are transmitted differentially over data channels, along with a clock. High-frequency loss and differential skew within a differential signal may be compensated by analog circuits embedded in the cable. These embedded circuits are tuned at production for best performance by observing the quality of the recovered analog signal. The embedded circuits are powered by a combination of power sources, both carried within the cable, and harvested from the high-speed signals themselves.

Programmable high-speed cable with printed circuit board and boost device

An HDMI cable may exhibit frequency dependent signal attenuation, inter symbol interference, and inter-pair skew. A boost device integrated with the cable can compensate for such impairments of the cable.

Programmable high-speed cable with boost device

A method for providing power to a boost device in a high-speed cable connected between a transmitting data source device and a receiving data sink device is described. The method comprises receiving differential data signals from the data source device in a differential input circuit of the boost device; boosting at least one of the received differential data signals into a boosted differential data signal; transmitting the boosted differential data signal from a differential output circuit of the boost device to the receiving data sink device; and obtaining power to operate at least some of the circuitry of the boost device from the data sink device through its connection with the differential output circuit, for example, providing at least some of the power to operate the processing block. A corresponding high-speed cable is also described.
