USB 2.0 Hi-Speed 7-Port Hub Controller
General Description
The SMSC 7-Port Hub is a low power, OEM
configurable, MTT (multi transaction translator) hub
controller IC with 7 downstream ports for embedded
USB solutions. The 7-port hub is fully compliant with the
USB 2.0 Specification and will attach to an upstream
port as a Full-Speed Hub or as a Full-/Hi-Speed Hub.
The 7-Port Hub supports Low-Speed, Full-Speed, and
Hi-Speed (if operating as a Hi-Speed Hub) downstream
devices on all of the enabled downstream ports.
General Features
Hub Controller IC with 7 downstream ports
High-performance multiple transaction translator
MultiTRAK™ Technology provides one transaction
translator per port
Enhanced OEM configuration options available
through either a single serial I
2
C
TM
EEPROM, or
SMBus Slave Port
64-Pin (9x9 mm) QFN lead-free, RoHS compliant
package
Hardware Features
Low power operation
Full Power Management with individual or ganged
power control of each downstream port
On-chip Power On Reset (POR)
Internal 1.8V Voltage Regulator
Fully integrated USB termination and Pull-up/Pull-
down resistors
On Board 24MHz Crystal Driver, Resonator, or
External 24MHz clock input
USB host/device speed indicator. Per-port 3-color
LED drivers indicate the speed of USB host and
device connection - hi-speed (480 Mbps), full-speed
(12 Mbps), low-speed (1.5 Mbps)
Enhanced EMI rejection and ESD protection
performance
OEM Selectable Features
Customizable Vendor ID, Product ID, and Device ID
Select whether the hub is part of a compound device
(When any downstream port is permanently
hardwired to a USB peripheral device, the hub is part
of a compound device.)
Flexible port mapping and disable sequence. Ports
can be disabled/reordered in any order to support
multiple product SKUs. Hub will automatically reorder
the remaining ports to match the Host controller's
numbering scheme
Programmable USB differential-pair pin location
— Eases PCB layout by aligning USB signal lines directly
to connectors
Programmable USB signal drive strength. Recover
USB signal integrity due to compromised system
environments using 4-level driving strength resolution
Select the presence of a permanently hardwired USB
peripheral device on a port by port basis
Configure the delay time for filtering the over-current
sense inputs
Configure the delay time for turning on downstream
port power
Indicate the maximum current that the 7-port hub
consumes from the USB upstream port
Indicate the maximum current required for the hub
controller
Support Custom String Descriptor up to 31 characters
in length for:
– Product String
– Manufacturer String
– Serial Number String
Pin Selectable Options for Default Configuration
— Select Downstream Ports as Non-Removable Ports
— Select Downstream Ports as Disabled Ports
— Select Downstream Port Power Control and Over-
Current Detection on a Ganged or Individual Basis
— Select USB Signal Drive Strength
— Select USB Differential Pair Pin location
Applications
LCD monitors and TVs
Multi-function USB peripherals
PC mother boards
Set-top boxes, DVD players, DVR/PVR
Printers and scanners
PC media drive bay
Portable hub boxes
Mobile PC docking
Embedded systems
