Overview
The TUSB7320IRKMT, produced by Texas Instruments, is a USB 3.0-compliant xHCI (eXtensible Host Controller Interface) host controller. This component is designed to interface with the host system through a PCIe x1 Gen 2 interface and supports up to two downstream USB ports. It is available in a 100-pin WQFN-MR package, making it suitable for various high-performance computing and server applications. The device does not require an external flash for its default configuration, although an optional serial EEPROM can be used for custom configurations. It also features internal spread spectrum generation and supports low-cost crystal or oscillator options.
