Isolated high-speed digital interface for vehicles

摘要

An apparatus and method for providing an isolated high-speed digital interface for communicating high-speed digital data within a vehicle. In architecture, the interface includes one or more input terminals and one or more output terminals. Each output terminal being associated with one of the one or more input terminals without any electrically conductive path existing between the output terminal and the input terminal, and instead the input terminal and the output terminal are coupled to one another by an optical coupling. The present invention can also be viewed as a method that can be broadly summarized by the following steps, providing at least one input terminal for receiving data and providing at least one output terminal. Wherein the output terminal is associated with the one input terminal without any electrically conductive path existing between the output terminal and the input terminal, are coupled to one another by an optical coupling.

1. An isolated unidirectional digital interface for vehicles for communicating digital data within a vehicle, the digital interface comprising:
one or more input terminals; one or more emitters associated with the one or more input terminals; a first power supply associated with the one or more emitters for powering the emitters; one or more detectors optically coupled to the one or more emitters; one or more output terminals, with each output terminal being associated with one of the one or more detectors, a second power supply associated with the one or more detectors for powering the detectors, and wherein the second power supply is electrically isolated from the first power supply; and wherein the digital interface is configured without any electrically conductive path existing between an output terminal and an input terminal, and instead the one or more input terminals and the one or more output terminals are coupled to one another by an optical coupling.
