ISP1122
Universal Serial Bus stand-alone hub
Rev. 03 — 29 March 2000
Product specification
1. General description
The ISP1122 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 ISP1122 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 ISP1122 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 ISP1122
has a serial I
2
C-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.
