PLX Technology, Inc. was founded in 1986 and is headquartered in Sunnyvale, California, USA. The company specializes in high-speed interconnect semiconductor solutions for data center, enterprise, and consumer applications. Its core expertise lies in PCI Express (PCIe) switches and bridges, enabling efficient multi-host communication and resource sharing. The flagship ExpressLane family of PCIe switches offers scalable, low-latency, and high-bandwidth connectivity, featuring lane counts from 3 to 96 lanes with advanced features like DMA and NTB. PLX also provides PCIe bridge chips that convert PCIe to other protocols such as USB, Ethernet, and general-purpose I/O, simplifying system design. The company's products are widely adopted in servers, storage arrays, networking equipment, and industrial PCs. Before its acquisition by Broadcom Corporation in 2014, PLX was the leading independent supplier of PCIe switches, holding significant market share. Today, its technology continues as part of Broadcom’s data center solutions group, serving top-tier cloud and enterprise OEMs. PLX’s innovations in switch fabric have set industry benchmarks for performance and power efficiency. With a strong patent portfolio and engineering heritage, it remains a key enabler of modern high-speed interconnect architectures.
