Introduction

The PI7C9X1172BLE is an interface controller that enables a PCI Express connection between a host processor and supported peripheral devices. This controller has numerous applications and its working principle helps to determine specific usage and applications. In this article, we’ll discuss the application field and working principle of the PI7C9X1172BLE.

Application Field

The PI7C9X1172BLE is used in a variety of applications, including Servers, Networking, Test & Measurement, Personal Computer, and Embedded Systems. It has a Low Pin Count (LPC) Interface, which allows for an easy and cost-efficient connection between the host system and the peripheral devices. Additionally, the PI7C9X1172BLE controller can be used to bridge the PCI Express bus to PCI Express-to-USBbridge, enabling the connection of additional USB devices to the host system.

The PI7C9X1172BLE is ideal for use in high-performance and highly demanding applications such as telecommunications, medical equipment, air traffic control systems, and defense applications. It is also suitable for consumer devices such as game consoles, TV sets and computers.

Working Principle

The PI7C9X1172BLE uses an integrated buffer memory to facilitate simultaneous transfer operations between the PCI Express bus and the USB bus. The controller itself consists of two parts – an internal controller that works with the PCI Express and an external controller that works with the USB. This separation of tasks enables it to handle both PCIe and USB interfaces at once and perform multiple complex tasks simultaneously.

The PI7C9X1172BLE supports data transfer rates of up to 12.5Gbps, complying with PCI Express 3.0. It supports the use of multiple data paths to move data simultaneously. For example, it can be used to perform simultaneous read and write operations on the same address and data line. This feature is useful for applications requiring high data transfer speed, such as video processing.

Also, the PI7C9X1172BLE supports multiple data widths, from x1 to x4, allowing for flexibility in interfacing with a variety of devices. This allows for higher performance, since more data can be transferred at one time. Additionally, it supports various protocols, such as SATA, USB 2.0, and USB 3.0, as well as data traffic migration and power management.

Conclusion

The PI7C9X1172BLE is an interface controller that facilitates the connection between a host processor and peripheral devices. It opens up a wide range of applications with its ability to bridge between PCIe and USB. This controller has numerous features, such as multiple data paths, multiple data widths, and various protocols, that make it great for high-performance applications.
