Abstract:
1. An application-specific integrated circuit for interfacing with an I/O device, the application-specific integrated circuit comprising: a pin interface for electrical signal communication; a data interface for digital data communication; a digital section in data communication with the data interface, the digital section comprising registers for storing digital data; and an analog section in electrical signal communication with the pin interface and digital data communication with the registers of the digital section, the analog section comprising multiple function-specific elements for processing an electrical signal that is communicated via the pin interface and a differential signaling element configured to convert a differential signal to a single-ended format, wherein one component of the differential signal is received on the pin interface and the other component of the differential signal is received via a matrix switch interface, wherein the analog section can be configured to establish one of multiple different function-specific processing paths in response to a configuration command received via the data interface.
