ISP1520 Hi-Speed Universal Serial Bus hub controller Rev. 02 — 04 May 2004 Product data 1. General description The ISP1520 is a stand-alone Universal Serial Bus (USB) hub controller IC that complies with Universal Serial Bus Specification Rev. 2.0. It supports data transfer at high-speed (480 Mbit/s), full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s). The upstream facing port can be connected to a Hi-Speed USB host or hub or to an Original USB host or hub. If the upstream facing port is connected to a Hi-Speed USB host or hub, then the ISP1520 will operate as a Hi-Speed USB hub. That is, it will support high-speed, full-speed and low-speed devices connected to its downstream facing ports.
