The PI7C9X762CLEX is a single-chip PCI Express bridge controller family developed by Pericom Semiconductor. It is a highly programmable, low-cost solution for configurable logic-to-logic, packet-oriented data transfers from PCI Express to other I/O interfaces. This bridge controller family, commonly found in various personal electronic devices, features a scalable architecture that supports devices with a variety of I/O interfaces, including PCIe 3.0, USB 3.0, SATA, XAUI and DDRx.

Application Field

This bridge controller has a wide range of applications in various devices, such as portable PCs, POS terminals, gaming consoles, servers, storage devices, network switches, media players, and embedded systems.

Since it supports a variety of I/O interfaces, the PI7C9X762CLEX bridge controller is well suited for many electronics applications that involve data transfers between PCs and a variety of peripherals. In addition, it has the ability to support the configuration and delivery of the full complement of PCIe features to remote I/O interfaces, making it suitable for applications such as PCIe bridges, buffer memory expansion, packet and frame bridging, packet switching, and many others.

Working Principle

The PI7C9X762CLEX bridge controller works by providing an interface between PCIe and another I/O interface, such as USB 3.0, SATA, XAUI, and DDRx. The bridge controller is a two-way bridge device that supports data transfers in both directions: from PCIe to I/O and from I/O to PCIe. It also has the capability to support a variety of I/O interfaces and can manage multiple types of data streams.

The PI7C9X762CLEX bridge controller operates in either of two modes: host mode or peripheral mode. In host mode, the bridge controller acts as the initiator of data transfers, sending requests to and receiving responses from the I/O interface. In peripheral mode, the bridge controller acts as the target of data transfers, receiving requests from and sending responses to the I/O interface.

In order to support the full range of PCIe features, the PI7C9X762CLEX bridge controller provides an intelligent bridge between PCIe and I/O interfaces. The bridge controller supports a scalable architecture, allowing for future applications with increased demands for I/O performance. It also supports both visible and invisible transactions, enabling higher throughputs between devices.
