Chapter 1. Overview
1.1 INTRODUCTION
The LAN9353 is a fully featured, three-port 10/100 managed Ethernet switch designed
for industrial and embedded applications where performance, flexibility, ease of inte-
gration and system cost control are required.
The LAN9353 combines all the functions of a 10/100 switch system, including the
switch fabric, packet buffers, buffer manager, media access controllers (MACs), PHY
transceivers, and serial management. IEEE 1588v2 is supported via the integrated
IEEE 1588v2 hard-ware time stamp unit, which supports end-to-end and peer-to-peer
transparent clocks.
The LAN9353 complies with the IEEE 802.3 (full/half-duplex 10BASE-T and
100BASE-TX) Ethernet protocol, IEEE 802.3az Energy Efficient Ethernet (EEE)
(100Mbps only), and 802.1D/802.1Q management protocol specifications, enabling
compatibility with industry standard Ethernet and Fast Ethernet applications.
100BASE-FX is supported via an external fiber transceiver and cable diagnostics
(short, open and length) is included on the internal twisted pair copper interface.
The EVB-LAN9353 is an Evaluation Board (EVB) that utilizes the LAN9353 to provide
a fully-functional three-port Ethernet switch with Single MII/RMII/Turbo MII or Dual
RMII. The EVB-LAN9353 provides one fully integrated MAC/PHY internet port (Port 2)
via on-board RJ45 connectors. Port 0 and Port 1 provides two MII port connectors
which support the following:
• An external “Dual RMII –Capable or singleMII / RMII / Turbo MII”-Capable MAC
(with LAN9353 in PHY mode), via the on-board 40-pin male MII connector
• An external “Dual RMII –Capable or singleMII / RMII / Turbo MII”-Capable PHY
(with LAN9353 in MAC mode), via the on-board 40-pin female MII connector
Power is supplied to the board via a +5V external wall mount power supply.
The EVB-LAN9353 includes a 64K x 8 I2C EEPROM that may be used to automatically
load configuration settings from the EEPROM into the device at reset. An I2C host
adapter interface header (10-pin, 2x5) is provided to simplify I2C based configuration.
A simplified block diagram of the EVB LAN9353 can be seen in Error! Reference
source not found and LAN9353 supports for CONFIG 9 or CONFIG 10.
CONFIG 9: used to configure the LAN9353 in Dual RMII mode for external ports.
CONFIG 10: used to configure the LAN9353 in Single MII/RMII/TMII mode for external
port.
