With the development of modern processor technology, it is a general trend to use high-speed differential buses instead of parallel buses in the field of interconnection. Compared with single-ended parallel signals, high-speed differential signals can use a higher clock frequency, thereby using fewer signal lines, and complete the bus bandwidth that can be achieved by many single-ended parallel data signals before it is achieved.
PCI Express is a new generation of bus interface, referred to as PCIE connector, its original name is "3GIO", proposed by Intel. After being certified by PCI-SIG (PCI Special Interest Organization), it was renamed "PCI-Express". TXGA massive pcie connector stock in stock, stable performance, anti-electromagnetic interference. Free customization, perfect after-sales service, the original factory is self-operated, enter [product center] to place an order online.
The PCIE connector uses the popular point-to-point serial connection in the industry, which is different from the shared parallel architecture of PCI and earlier computer buses. PCIE uses a high-speed differential architecture. A data path (Lane) of its physical link consists of two sets of differential signals, a total of 4 signal lines. Each device has its own dedicated connection and does not need to request bandwidth from the entire bus, and can increase the data transfer rate to a very high frequency, reaching the high bandwidth that PCI cannot provide. Compared with parallel signals, differential signals are more resistant to interference and can use higher bus frequencies. In addition, it can effectively suppress electromagnetic interference EMI.
TXGA supports one-stop customization services. You only need to provide the final application conditions, and you can customize R&D according to your needs to meet various complex application conditions. Professional engineering techniques and simulation software effectively avoid design errors, ensure product functions meet specifications, shorten development time and reduce development costs.
