PLX Technology是一家位于加利福尼亚州桑尼维尔的集成电路公司。 PLX产品专注于PCI Express和以太网技术。

Broadcom Limited，原Avago Technologies，于2014年8月12日完成对PLX Technology的收购。

PLX提供用于互连计算机系统部件的组件。

PCI Express

PLX Technology PEX8606 PCI Express开关位于PCI Express×1卡上，可在一个端点之外创建多个端点，并允许多个设备共享
外围组件互连（PCI）总线演变为由PCI-SIG标准组标准化的一系列技术。软件与先前的并行技术兼容，交换式串行PCI Express（PCIe）技术成为到2008年连接大多数计算机系统构建模块的流行方式。

开关：由于PCI Express是点对点串行互连标准，因此需要一个开关将一个PCI Express端口从处理器或芯片组连接到多个端点。 PLX从2004年开始使用PCIe 1.0系列，每秒2.5 Gigatransfers，2007年末推出PCIe 2.0产品，数据速率翻倍，达到每秒5.0 Gigatransfers。该公司提供超过18种PCIe 3.0产品，每秒8 Gigatransfers。主板制造商可以选择安装此类芯片，以增加可用PCIe通道的数量。

桥接：PCI Express桥接器使使用PCI Express的系统能够与使用其他标准的设备协同工作。这种类型的桥接器便于连接回传统PCI以进行升级。使用这些桥接设备的应用程序包括服务器，存储主机总线适配器，图形，电视调谐器和安全系统。 PLX还提供了几种传统桥，可以转换通用串行和并行端口。 PLX于2011年1月宣布推出一款将PCI Express连接到USB 3.0的控制器。

消费者
PLX于2009年1月收购牛津半导体公司，为消费者存储设计和制造网络附加存储和直接连接存储硬件和固件，但于2011年10月将其位于英国泰晤士河畔阿宾登的研发团队剥离给OCZ科技集团。

以太网络
PLX于2010年9月以约2600万美元的价格收购了Teranetics公司。此合并产品支持物理层连接到10千兆以太网，称为10GBASE-T，使用6类电缆或7类电缆。 PLX于2012年9月将该团队驱逐至Aquantia Corporation。

PLX Technology is an integrated circuit company based in Sunnyvale, California. PLX products are focused on PCI Express and Ethernet technologies.

Broadcom Limited, formally Avago Technologies, completed acquisition of PLX Technology on August 12, 2014.

PLX supplies components for interconnecting parts of computer systems.

PCI Express

PLX Technology PEX8606 PCI Express switch on a PCI Express ×1 card, creating multiple endpoints out of one endpoint and allowing it to be shared by multiple devices
The Peripheral Component Interconnect (PCI) bus evolved into a family of technologies standardized by the PCI-SIG standards group. Software compatible with the previous, parallel technology, the switched serial PCI Express (PCIe) technology became a popular way to connect the building blocks of most computer systems by 2008.

Switches: Since PCI Express is a point-to-point serial interconnect standard, it requires a switch to connect a single PCI Express port from a processor or chipset to multiple end-points. PLX started with the PCIe 1.0 family at 2.5 Gigatransfers per second in 2004, followed by PCIe 2.0 products in late 2007, where the data rate doubled to 5.0 Gigatransfers per second. The company offers more than 18 PCIe 3.0 products at 8 Gigatransfers per second. Such chips can be optionally installed by motherboard manufacturers to increase the number of available PCIe lanes.

Bridges: A PCI Express bridge enables a system that uses PCI Express to work with devices that use other standards. This type of bridge facilitates connection back to conventional PCI for upgrading. Applications using these bridge devices include servers, storage host bus adapters, graphics, TV tuners and security systems. PLX also offers several legacy bridges that translate general purpose serial and parallel ports. PLX announced a controller that connects PCI Express to USB 3.0 in January 2011.

Consumer
PLX, through its acquisition of Oxford Semiconductor in January 2009, designed and manufactured network-attached storage and direct attached storage hardware and firmware for consumer storage  but divested its research and development team in Abingdon-on-Thames, UK, in October 2011 to OCZ Technology Group.

Ethernet
PLX purchased the Teranetics company in September 2010 for about $26 million. Products from this merger supported physical layer connection to 10 Gigabit Ethernet known as 10GBASE-T, using Category 6 cable or Category 7 cable. PLX divested this team in September 2012 to Aquantia Corporation.
