ISP1122A
Universal Serial Bus stand-alone hub
Rev. 01 — 27 March 2000
Preliminary specification
1. 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 (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.
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.
