2-Port USB 2.0 Hi-Speed Hub Controller

Datasheet

PRODUCT FEATURES

General Description

Highlights



High performance, low-power, small footprint hub

controller IC with two downstream ports

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.



Fully compliant with the USB 2.0 Specification

Optimized for minimal bill-of-materials and low-cost

designs

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.

Applications



LCD monitors and TVs

Multi-function USB peripherals

PC motherboards

Set-top boxes, DVD players, DVR/PVR

Printers and scanners

PC media drive bay

Portable hub boxes
