ISP1122A General Description

The ISP1122A is a stand-alone Universal Serial Bus (USB) hub device which complies with USB Specification 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 configurable 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 (V_BUS), 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.

The ISP1122A has built-in overcurrent sense inputs, supporting individual and global overcurrent protection for downstream ports. All ports (including the hub) have GoodLink™ indicator outputs for easy visual monitoring of USB traffic. The ISP1122A has a serial I2C-bus interface for external EEPROM access and a reduced frequency (6 MHz) crystal oscillator. These features allow significant cost savings in system design and easy implementation of advanced USB functionality into PC peripherals.
