Abstract: A system and method for synchronization of touch-panel devices is described. In one embodiment, the system includes a first controller device configured to control operations of a first portion of a touch-panel device such that the first controller device is further configured to generate a single master timing signal. The single master timing signal is configured to synchronize operation of the first controller device and a second controller device that is configured to control operations of a second portion of a touch-panel device.

Abstract: A controller circuit provides communication paths between multiple host devices and a target device. The controller circuit includes a first host idle detection circuit that determines when a first host interface (I/F) is in an idle state, an idle state being when the first host I/F is not communicating with the controller circuit. A switch circuit can selectively enables a controllable communication path between a second host I/F and a target device I/F. A first response circuit can be coupled to the first host I/F and output predetermined responses from the first host I/F in response to communications received on the first host I/F. The first response circuit outputting a predetermined response when at least the controller circuit has enabled the controllable communication path between a second host I/F and the target device I/F and disabled the controllable communication path between the first host I/F and the target device I/F.

Abstract: An apparatus coupled to a low speed tester and a device is disclosed. The device may have a first speed faster than a second speed of the low speed tester. The apparatus may be configured to allow the low speed tester to perform high speed tests of the device at the first speed.

Abstract: An apparatus comprising one or more storage elements. The one or more storage elements may be configured to switch an input/output between a first domain and a second domain in response to one or more control signals.

Abstract: A circuit that may be configured to store data and interface with an external device. The circuit may provide one or more control signals to the external device.

Abstract: A USB device for communicating data from the device to a USB host is provided. The USB device may have an interrupt or isochronous endpoint for communicating interrupts to the host and a bulk data endpoint for communicating bulk data to the host. The USB device may communicate a signal over the interrupt or isochronous endpoint to the host indicating that the device has bulk data to communicate to the host and may communicate bulk data over the bulk endpoint in response to bulk data requests from the host generated based on the signal over the interrupt or isochronous endpoint.

Abstract: A device and method for interconnecting two universal serial buses (USBs) is provided in which the device controls the current supplied to the device from the USBs via a power manager. In particular, when one or both of the buses connected to the device enter a suspended state, the power manager reduces the current consumed by the device so that the device does not exceed a maximum suspend current. The device may also have a power manager controller which permits one or both device drivers connected to the USBs to control the power manager.

Abstract: A USB-to-USB connecting device is provided for interconnecting two independent universal serial buses (USBs) and for synchronizing local device clocks to the data streams of both USBs. To interconnect the USBs, the device may include a separate local clock synchronization mechanism for each USB connected to the device. Each separate local clock synchronization may utilize the same reference clock. A method for interconnecting two USBs is also provided.
