PRODUCT FEATURES

General Description

The SMSC USB2422 hub is a low-power, single transaction

translator, hub controller IC with two downstream ports for

embedded USB solutions. The SMSC hub controller can

attach to an upstream port as a Hi-Speed and Full-Speed

hub or as a Full-Speed only hub. The SMSC hub supports

Low-Speed, Full-Speed, and Hi-Speed (when configured as

a Hi-Speed hub) downstream devices on the enabled

downstream ports.

All required resistors on the USB ports are integrated into

the hub. This includes all series termination resistors on D+

and D- pins and all required pull-down and pull-up resistors

on D+ and D- pins. The over-current sense inputs for the

downstream facing ports have internal pull-up resistors.

Features



Supports the USB Battery Charging Specification,

Revision 1.1



Fully integrated USB termination and pull-up/pull-

down resistors



Supports a single external 3.3 V supply source;

internal regulators provide 1.2 V internal core voltage



On-chip driver for 24 MHz crystal resonator or

external 24 MHz clock input



ESD protection up to 6 kV on all USB pins



Supports self-powered operation



SMSC hub contains a built-in default configuration;

no external configuration options or components are

required



Downstream ports as non-removable ports



Downstream port power control and over-current

detection on an individual or ganged basis



Supports compound devices on a port-by-port basis



24-pin SQFN (4x4 mm), RoHS-compliant package
