What is PCI Express?

PCI Express is the full name of our common PCI-E interface, and is the new generation of bus interface (PCIE of graphics card, sound card and solid state hard disk is more common). The interface specification was proposed at the Intel Developer Forum in 2001 (more than 20 industry-leading companies including Intel, AMD, DELL and IBM began to draft new technical specifications), and was officially launched in 2004. The following is a detailed description of PCI Express.



PCI Express is a new bus interface used to replace PCI, which has reached the bottleneck in improving the system performance. It can provide extremely high bandwidth and meet the system requirements. PCI-E bus supports bidirectional transmission mode and data channel transmission mode. The data sub-channel transmission mode is x1, x2, x4, x8, x12, x16 multi-channel connection of PCI-E bus. The one-way transmission bandwidth of x1 can reach 250MB/s, and the two-way transmission bandwidth can reach 500MB/s.


At present, PCI-E X1 and PCI-E X16 are the mainstream specifications of PCI-E, and many chipset manufacturers have added support for PCI-E X1 among Nanqiao chips. PCI-E also supports high-level power management, hot plug, synchronous data transmission, and bandwidth optimization for priority data transmission. Almost all personal computers, notebooks and commercial servers use PCIE as the main interface to connect processors and expansion cards.


When the equipment with PCIE interface needs external data exchange or remote control, it needs serial communication cable. According to PCIE's D-Sub interface types, such as DB9, DB15, DB25, DB26, DB37, DB44, DB62, etc., Premier Cable provides MOXA-compatible D-Sub series cable harnesses: CBL-M37M9x4-30, CBL-M44M9x4-50, CBL-M62M9x8-100, etc.


According to the market demand, the D-sub to USB cable with chips has been developed, such as DB37 to DB9 RS232 Serial Cable, which is compatible with CBL-M37M9x4. It simplifies the design of multiple lines and can be used for controlling keypads, cameras, touch screens and printers in ATMs, directing security cameras in an office or warehouse, running cash registers, receive printers and credit card machines in a store or restaurant.


Premier Cable focuses on the customized research and development of connectors and harnesses. It can achieve matching and customization on demand, scientifically analyze and judge the application needs of harnesses in various fields, and provide you with cost-effective, high-quality customized cable assembly solutions.
