The 4030MX and 4320MX multiplexers and 4021DX and 4321DX demultiplexers achieve data rates up to 43 Gbps in optical networking designs. The 4020MX mux accepts four differential data channels at 10 Gbps while the 4320MX mux takes in four 10.75-Gbps channels. The 4021DX and 4321DX demuxes convert data streams back to four differential outputs of 10 and 10.75 Gbps, respectively. Designers can combine the muxes and demuxes with the company's TIA as and modulators to receive a complete chip set for OC-768 designs.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
