Abstract: A circuit includes signal conditioner circuitry, level shifter circuitry, and state detector and controller circuitry coupled between the signal conditioner circuitry and the level shifter circuitry. The state detector and controller circuitry includes receiver circuitry and a finite state machine coupled to the receiver circuitry. The finite state machine is configured to detect a first data rate from signals, control operation of the signal conditioner circuitry responsive to detecting the first data rate, and control operation of the level shifter circuitry during a second data rate.

Abstract: A method includes determining a charging port mode by receiving a data contact detect (DCD) Complete signal, reducing a voltage on a first data pin of a Universal Serial Bus (USB) connector of a portable device, and determining that a condition is true when a voltage on a second data pin of the USB connector is equal to or greater than 0.8 to 2.0 Volts (V), and is false otherwise. When the condition is true, a first signal is sent on a control circuit output indicating indicate that the PD is connected to a dedicated charging port (DCP) of Divider 0 mode. When the condition is false, a second signal is sent on the control circuit output indicating that the PD is connected to a DCP of 1.2V short mode.

Abstract: In an example, a data communication device includes one or more receivers, and one or more transmitters. The data communication device detects a start of frame packet (μSOF) on a data bus, wherein the μSOF indicates the start of a microframe; determines whether there are any data packets contained in the microframe during a first threshold period after the μSOF; and detects that there is no data packet contained in the microframe during the first threshold period after the μSOF, and in response, transitions at least one of the one or more transmitters from an active state to an OFF state, and transitions the at least one of the one or more transmitters from the OFF state to the active state prior to a switchback period before the end of the microframe.

Abstract: A method of operating an embedded universal serial bus (eUSB) repeater includes holding an eUSB receiver and a USB transmitter in active states and holding a USB receiver and an eUSB transmitter in standby states. The method includes receiving by the eUSB receiver a token packet indicative of transmission of a first downstream packet, and transitioning the USB receiver and the eUSB transmitter from the standby states to the active states responsive to the token packet. The method includes transmitting the token packet by the USB transmitter. The method includes receiving by the eUSB receiver a downstream packet or receiving by the USB receiver an upstream packet within a first timeout period after receiving the token packet, and transmitting the downstream packet by the USB transmitter or transmitting the upstream packet by the eUSB transmitter.

Abstract: This disclosure generally relates to USB TYPE-C, and, in particular, DISPLAYPORT Alternate Mode communication in a USB TYPE-C environment. In one embodiment, a device determines a DISPLAYPORT mode and determines an orientation of a USB TYPE-C connector plug. A multiplexer multiplexes a DISPLAYPORT transmission based in part on the determined orientation of the USB TYPE-C connector plug.

Abstract: A method of operating an embedded USB2 (eUSB2) repeater includes receiving a downstream packet at a USB2 port and transitioning a USB transmitter from an idle state to a standby state responsive to receiving the downstream packet. The method further includes transitioning the USB transmitter from the standby state to an active state if an upstream packet is received at an eUSB2 port within a first time period of receiving the downstream packet and transmitting the upstream packet. The method also includes transitioning the USB transmitter from the active state to the standby state after transmission of the upstream packet. The method also includes transitioning the USB transmitter from the standby state to the idle state if more upstream packets are not received at the eUSB2 port within a second time period.

Abstract: Aspects of the disclosure provide for a method. In at least some examples, the method includes receiving, at a circuit, data via a differential input signal. The method further includes detecting a falling edge in the data received via the differential input signal. The method further includes holding an output of the circuit at a final logical value of the data. The method further includes disabling a transmitter of the circuit while holding the output of the circuit at the final logical value of the data. The method further includes releasing the output of the circuit from the final logical value of the data.

Abstract: A Universal Serial Bus (USB) adapter includes a USB hub and a USB switch. The USB hub includes a plurality of downstream ports and one upstream port. The USB switch includes a plurality of connections that comprise a first connection configured to be coupled to a first USB apparatus, a second connection configured to be coupled to a second USB apparatus, a third connection coupled to the USB hub's upstream port, and a fourth connection coupled to one of the USB hub's downstream ports. The USB switch is configured to establish a first communication path between the first and second connections that bypasses the USB hub based on a determination that the first USB apparatus is to operate as a USB host, and to establish a second communication path through the USB hub based on a determination that the first USB apparatus is to operate as a client device.
