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 speed video cable carries signals according to the High-Definition Multimedia Interface (HDMI), and includes a raw cable and may include a boost device. The raw cable includes coaxial lines which are covered by an outer metallic braid. Each of four high speed video signals is 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, as well as the braid of the cable.

Economical boosted high speed data cable

A high speed video cable carries signals according to the High-Definition Multimedia Interface (HDMI), and includes a raw cable and a boost device. Each of four high speed video signals is carried on the inner conductors of a pair of coaxial lines in the raw cable. The boost device receives only one of the polarities of one of the high speed video signals, and generates a differential signal therefrom. Lower speed signals are carried on the galvanically or capacitively coupled shields of a pair of coaxial lines.

High speed data cable including a boost device for generating a differential 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 may include a boost device. The raw cable includes coaxial lines of a characteristic cable impedance higher than the impedance implied in the standards. The correct impedance is observed at the sending end by shunt resistors mounted in the first cable connector. The resultant loss of signal may be made up with the boost device mounted in the connector at the other end of the cable in the case of a long cable.

High speed data cable with impedance correction

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

Low cost high speed data cable

One example of an ESD protection circuit () can include a p-channel field effect transistor (PFET) () having a source-drain path connected between a pad () and a protected circuit (). In an ESD event, PFET () can provide an ESD discharge path between pad () and a high power supply node () or low power supply node ().

Electrostatic discharge (ESD) circuit and method that includes P-channel device in signal path

An architecture and method are provided for preventing snapdown in a voltage controlled MEMS device having a movable actuator with an actuator electrode coupled to a high voltage power supply (HVPS) through a drive circuit, the movable actuator suspended over a cavity electrode formed on a substrate and coupled to a common backplane supply (VssC). Generally, the circuit includes a number of first diodes coupled between the HVPS and the actuator electrode and/or the cavity electrode to provide a forward-biased path to transfer a positive charge to the HVPS when the accumulated charge exceeds a predetermined threshold. Preferably, the drive circuit further includes second diodes to provide a low impedance path to transfer a positives charge from the actuator electrode and/or the cavity electrode to a substrate ground when the accumulated charge results in or exceeds a predetermined threshold voltage. Other embodiments are also disclosed.

Snapdown prevention in voltage controlled MEMS devices

The present invention concerns an apparatus comprising a first circuit and a second circuit. The first circuit may be configured to generate a reference output voltage in response to a plurality of reference voltages. The second circuit may be configured to generate an output voltage in response to the reference output voltage and an unknown voltage. The output voltage may comprise accurately controlled hysteresis.
