Abstract: A circuit that supports multiple monitors, docking functions, and protected content via one cable. The circuit includes a receiver that receives multiple video streams, each including respective video data, a mux/demux, coupled to the receiver, that determines which video stream to display on a monitor, a display interface coupled to the first mux/demux, wherein the display interface is configured to generate output signals based on the video data of the determined video stream to be displayed on the first monitor, a transmitter coupled to the mux/demux, and a transmit physical interface (TPI) coupled to the transmitter. The mux/demux sends at least a remainder of the video streams to the transmitter, which sends them to the TPI, which transmits them as output, useable as input to further instances of the circuit.

Abstract: A circuit that supports multiple monitors, docking functions, and protected content via one cable. The circuit includes a receiver that receives multiple video streams, each including respective video data, a mux/demux, coupled to the receiver, that determines which video stream to display on a monitor, a low-voltage differential signaling (LVDS) converter, coupled to the mux/demux, that generates an LVDS signal based on the video data of the determined video stream, an LVDS serializer/deserializer, coupled to the LVDS converter, that generates a signal based on the LVDS signal and sends the signal to a display panel of the monitor for display, a transmitter coupled to the mux/demux, and a transmit physical interface (TPI) coupled to the transmitter. The mux/demux sends at least a remainder of the video streams to the transmitter, which sends them to the TPI, which transmits them as output, useable as input to further instances of the circuit.

Abstract: A USB-to-Ethernet controller with a USB hub may be integrated into a single integrated circuit (IC) USB-Ethernet Combination (UEC) device. The UEC may provide the end user with an Ethernet port, multiple downstream USB ports, and an upstream USB port for connecting to a USB host controller. One or more of the USB hub ports may be brought off the IC, enabling an end user to connect them to any arbitrary USB device(s). The third hub port may be an internal downstream port without a physical layer, and may be configured to connect to an Ethernet controller, which may comprise a USB device controller. The Ethernet controller may connect to the internal downstream port via a digital interface such as UTMI. The UEC device may appear to the host computer as two separate devices, an Ethernet controller and a USB hub. The Ethernet controller may appear as a permanently attached device on the internal downstream port.

Abstract: Serial bus hub with one or more low power devices. The serial bus hub may include at least one upstream port for coupling to a host system. The serial bus hub may include one or more downstream ports for coupling to peripheral devices. The serial bus hub may include the low power devices which may have no functionality external to the serial bus hub. The presence of the low power devices may allow the serial bus hub to draw additional power from the host system and a substantial portion of the additional power may be usable by other devices. The serial bus hub may be configured to allow the host system and one or more peripheral devices coupled to the one or more downstream ports to communicate.

Abstract: In one embodiment, provided is a method that includes detecting disconnect of a link at a Universal Serial Bus (USB) device coupled to a USB host via a USB bus, disconnecting the USB device from the USB bus, and modifying a power state of the USB device to a reduced power state. Disconnecting the USB device from the USB bus includes configuring the USB device such that the USB host recognizes the USB device as being disconnected from the USB bus. The reduced power state allows the USB device to monitor a status of the link such that the USB device is able to detect a reconnect of the link.
