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.

Chapter 2. Board Details
2.1 BOARD DETAILS
The following sections describe the various board features, including jumpers, LEDs,
test points, system connections, and switches. A top view of the EVB-LAN9353 is
shown in Figure 2-1.
FIGURE 2-1: LAN9353 BOARD REV-A
2.1.1 Power
DC 5V is applied through (J1) DC Socket, powered by a +5V external wall adapter.
switch (SW1) need to be ON position for the 5V to reach the 3.3V regulator. Glowing of
Green LED (D1) indicates successful generation of 3.3V o/p. This Power is supplied to
the LAN9353 and it has internal 1.2 V regulator which supplies power to the internal
core logic.
2.1.2 Power-on Reset
A power-on reset occurs whenever power is initially applied to the LAN9353 or if the
power is removed and reapplied to the LAN9353. This event resets all circuitry within
the LAN9353. After initial power-on, the LAN9353 can be reset by pressing the reset
switch (SW2). The reset LED D2 will assert (red) when the LAN9353 is in reset condi-
tion.

For stability, a delay of approximately 180ms is added from the +3.3V o/p to reset
release.
2.1.3 Clock
The LAN9353 requires a fixed-frequency 25 MHz clock (±50 ppm) source for use by
the internal clock oscillator and PLL. This is typically provided by attaching a 25 MHz
crystal to the OSCI and OSCO pins. Optionally, this clock can be provided by driving
the OSCI input pin with a single-ended 25 MHz clock source.

Chapter 3. Board Configuration
3.1 STRAP OPTIONS
The following tables describe the default settings and jumper descriptions for the
EVB-LAN9353. These defaults are the recommended configurations for evaluation of
the LAN9353. These settings may be changed as needed, however, any deviation from
the defaults settings should be approached with care and knowledge of the schematics
and datasheet. An incorrect jumper setting may disable the board.
3.1.1 Jumpers J4:J15
Jumpers J4 through J15 set various functions of the LAN9353. They can also be used
as GPIOs, LED drivers. When used as LED drivers, as they are on the EVB-LAN9353,
they are connected a specific way to set the strap value to a “1”, and another way to
set the strap value to a “0” Figure 3-1 illustrates the schematics connections with the
D3 circuit as a pull-up, and the D4 circuit as a pull-down. To illuminate D3, the LAN9353
will drive the cathode of the D3 low. To illuminate D4, the LAN9353 will drive the cath-
ode of the D4 high.
The J4 - J15 jumpers must be configured in pairs to identical settings in order to realize
the D3 circuit or the D4 circuit. The pairings are as follows:
-J4 & J7
-J6 & J9
-J5 & J8
- J11 & J14
- J10 & J13
- J12 & J15
The following subsections detail the jumper pair settings, their associated strap set-
tings, and the functional effects of setting the straps. All strap values are read during
power-up and on the rising edge of nRST signal. Once the strap value is set, the
LAN9353 will drive the LED’s high or low for illumination according the strap value. For
other designs which may use these pins as GPIOs refer to LAN9353 datasheet for
additional information. In those cases, internal default straps must be changed by an
I2C or SMI master or through EEPROM fields.

3.1.8 I2C Aardvark® Header
J16 connector is used for I2C Aardvark header. Respective pin details are given below
in Table 3-17.
3.1.9 Copper and Fiber Mode Selections
The LAN9353 supports 100BASE-TX (Copper) and 100BASE-FX (Fiber) modes. In
100BASE-FX operation, the presence of the receive signal is indicated by the external
transceiver as either an open-drain, CMOS level, Loss of Signal (SFP) or a LVPECL
Signal Detect (SFF).
This EVB supports 100BASE-TX (Copper) and 100BASE-FX (Fiber) in SFP mode. By
default Copper Mode is active. Fiber Mode is supported as an assembly option. To
select the Copper or Fiber Mode, the respective strap and signal routing resister
assembly options must to be configured.
3.1.9.1 COPPER MODE
The EVB-LAN9353 is set to Copper Mode by default. Table 3-18 details the required
strap resistors settings for Copper Mode operation.
Additionally, the signal routing resistors detailed in Table 3-19 must be assembled for
Copper Mode operation.
3.1.9.2 FIBER MODE
The LAN9353 supports SFP type 100BASE-FX mode. To enable Fiber Mode, the
respective strap and signal routing resisters must be configured.
