The USB2517-JZX is a 7-port USB 2.0 high-speed Hub Controller. Leveraging Microchip's innovative MultiTRAK technology that delivers industry-leading data throughput in mixed-speed USB environments, the USB251x family is designed for applications that demand low power and a small footprint without compromising on performance. The 7-port hub is fully compliant with the USB 2.0 specification and will attach to an upstream port as a full-speed hub or as a full-/high-speed hub. The 7-port hub supports low-speed, full-speed and high speed (if operating as a high speed hub) downstream devices on all of the enabled downstream ports.
