Integrated optical-electronic interface in programmable integrated circuit device

摘要

Systems that provide integrated circuit device circuitry having an integrated optical-electronic interface for high-speed off-device communications are provided. An optical-electronic interface may be incorporated into an integrated circuit device, freeing up some or all of the electrical I/O pins of the integrated circuit device. Transceiver I/O channels may be provided on an integrated circuit device that can be switched between electrical and optical transceiver I/O channels.

主权项

1. Integrated circuit device circuitry comprising:
core circuitry comprising a plurality of groups of high speed input/output channels, wherein each of the input/output channels of one of the plurality of groups is coupled to the output of a respective multiplexer, and wherein each of the multiplexers selects between an optical interface and an electrical interface based on a control signal from circuitry outside of the integrated circuit device circuitry; a receiver optical control circuitry coupled to the core circuitry; and a plurality of electrical input/output ports coupled to the core circuitry and integrated with the integrated circuit device circuitry, wherein none of the electrical input/output ports are consumed by the receiver optical control circuitry.
