Abstract:
1. A fan-in integrated circuit of a node comprising: an arbiter/multiplexer; a plurality of receivers, each receiver electronically connected to the arbiter/multiplexer, wherein each receiver is configured to receive optical signals over a corresponding optical broadcast bus and convert the optical signals into a data stream encoded in electronic signals, and each receiver comprises an array of photodetectors, where each photodetector receives and converts one of the optical signals into analog electronic signals, and wherein the arbiter/multiplexer selects one receiver at a time to send the electronic signals to the arbiter/multiplexer which outputs the electronic signals to the node for processing; wherein a receiver further comprises: a trans-impedance amplifier (“TIA”) array, each TIA is electronically connected to a photodetector and amplifies the analog electronic signals output from the photodetector; a sampler array, each sampler electronically connected to a TIA of the TIA array and converts the analog electronic signals into digital electronic signals; and an address filter electronically connected to the sampler array that checks the destination address of packets encoded in the digital electronic signals and discards the data encoded electronic signals not destined for the node.
