Universal Serial Bus Stand-alone Hub

The ISP1122A is a stand-alone Universal Serial Bus (USB) hub device which complies with USB Specication Rev. 1.1. It integrates a Serial Interface Engine (SIE), hub repeater, hub controller, USB data transceivers and a 3.3 V voltage Regulator It has a congurable number of downstream ports, ranging from 2 to 5. The ISP1122A CAN be bus-powered, self-powered or hybrid-powered. When it is hybrid-powered the hub functions are powered by the upstream power supply (VBUS), but the downstream ports are powered by an external 5 Volt supply. The low power consumption in suspend mode allows easy design of equipment that is compliant with the ACPI, OnNow and USB Power Management requirements. By NXP Semiconductors
