SMSC’s LAN951x is the industry’s first family of fully-integrated, Hi-Speed USB 2.0 hub and high-performance 10/100 Ethernet
controllers. The LAN951x is specifically designed to provide system architects with a low-cost, power-efficient, small-footprint USB
to Ethernet and multi-port USB connectivity solution in a single package.
The LAN951x contains a Hi-Speed USB 2.0 hub with two (LAN9512), three (LAN9513) or four (LAN9514) fully-integrated downstream
USB 2.0 PHYs, an integrated upstream USB 2.0 PHY, a 10/100 Ethernet MAC/PHY controller and an EEPROM controller. It offers
SMSC’s highest level of USB 2.0 and 10/100 Ethernet compliance and interoperability. Additionally, the LAN951x devices simplify
system design by leveraging the existing USB stack and reducing the PCB footprint by up to 65% compared to discrete competitive
solutions. USB-based networking technology offers a cost-effective and smart design alternative to traditional PCI/PCI-Express
networking solutions due to the flexibility of routing and placement of Ethernet and USB connectivity ports.
SMSC’s complimentary and confidential LANCheck® and USBCheckTM online design review services are available for customers who
have selected our products for their application design-in*.
Fully-integrated, 2/3/4-port Hi-Speed USB 2.0 hub and 10/100
Ethernet controllers
SMSC’s UniClock™ technology simplifies the clocking scheme
and reduces system BOM cost by using a single 25MHz crystal
for both USB and Ethernet connectivity − without the need for
extra components when adding USB hubs
Built-in ±8kV/15kV contact/air discharge ESD protection on
both USB and Ethernet PHYs
24MHz clock out provided to connect additional USB Hubs
Multiple Operation Systems supported including: Windows® 7,
Windows XP, Windows Vista®, Windows CE, Windows Mobile®,
Linux® and Mac®, among others
Industrial temperature range (-40° to 85°C) options available
(LAN9512i/9513i/9514i)
Compact 9x9mm, RoHS-compliant, 64-pin QFN package
EEPROM-less design option helps to reduce BOM costs

Key Features
Single-chip 10/100 Ethernet controller and Hi-Speed USB 2.0 hub Reduces system cost when both USB and Ethernet connectivity are required
Dedicated TT for each USB downstream port Provides maximum USB throughput for each connected device when
operating with mixed-speed peripherals
USB PHYBoost technology Facilitates restoration of USB signal integrity which is impacted by poor
PCB layout, long cable and other system level variables
Single crystal design for USB and Ethernet; EEPROM-less design option Reduces BOM cost and PCB space
24MHz clock out If the system requires an additional USB hub, then the cost of an
additional crystal can be saved
Ethernet power save mode System SoC power can be saved by enabling additional power save modes
if the link is down or Ethernet is not active
Benefits
Universal Docking Station: The LAN9514 can be designed into
a USB docking station for laptops; provides USB port expan-
sion for Ethernet, video, audio, I/O and other optional USB
connectivity.

Internal DTV Solution: The LAN9512 can be used to provide
10/100 Ethernet and two additional USB 2.0 ports to DTV
applications. It provides a clean interface to the DTV’s SoC and
reduces the SoC pin-count for peripheral connectivity.
