Abstract: A termination network circuit for a differential signal transmitter comprises a plurality of n resistance elements and a plurality of differential signal drivers. A first end of each of the resistance elements is coupled at a common node, where n is an integer value and is the number of conductors used to transmit a plurality of differential signals. Each differential signal driver may include a positive terminal driver and a negative terminal driver. The positive terminal driver is coupled to a second end of a first resistance element while the negative terminal driver is coupled to a second end of a second resistance element. The positive terminal driver and the negative terminal driver are separately and independently switchable to provide a current having a magnitude and direction. During a transmission cycle each of the resistance elements has a current of a different magnitude and/or direction than the other resistance elements.

Abstract: System, methods and apparatus are described that facilitate transmission of data, particularly between two devices within electronic equipment. The apparatus may dynamically configure the communications link by determining a first set of connectors to carry a first data payload in a plurality of multi-phase signals, encoding the first data payload in a sequence of symbols, and transmitting the sequence of symbols on the first set of connectors. Each symbol may be characterized by a combination of phase state and polarity of a pair of connectors, and by a selection of at least one undriven connector. The number of connectors in the first set of connectors may be calculated to satisfy one or more of a bandwidth requirement and a maximum power consumption restriction.

Abstract: System, methods and apparatus are described that facilitate data link shutdown between two devices within an electronic apparatus, enabling safe entry into a hibernation mode. A host device transmits a command to a client device over a first data link. If the client device is not transmitting over the second data link, the host devices initiates shut down of the first data link and entry to a hibernation state. A delay may be initiated when it is determined that the client device is transmitting on the second data link. The command may comprise an instruction revoking permission to transmit data over a second data link to cause the client device to terminate communication on the second data link.
