4.0 Hardware Description
The KSZ8765CLX-EVAL board is in a compact form factor and can sit on a bench near a computer
with USB connector. There are three options for configuration: strap in mode; SPI mode and MDIO
mode. Strap-in mode configuration is easily done with on board jumper options. SPI mode and
MDIO mode are accomplished through a built in USB port interface. Using Micrel SPI and MDIO
software and your PC, you can configure the KSZ8765 device on board by the USB port. Using
Micrel SPI software and your PC, you can access the KSZ8765’s full feature set registers by the
USB to SPI interface. Or using Micrel MDC/MDIO software with your PC, you can access the
KSZ8765’s MIIM PHY registers by general MDC/MDIO interface. The board also features the
connectors for the Switch GMII/RGMII/MII/RMII interface and a Gigabit port for port 5. These are
to facilitate connections from the switch to an external MAC/GMAC or PHY/GPHY.
The KSZ8765CLX-EVAL board is easy to use. There are programmable LED indicators for link
and activity on all ports and a power LED. A manual reset button allows the user to reset the board
without removing the power plug. A standard 5VDC power supply can be used by the power jack so
that the user can supply power from any 110-240 Volt AC wall or bench socket, and the power also
can be provided by USB port when close pin 2-3 of the JP40 jumper.

4.1 Strap in Mode
Strap in configuration mode is the quickest and easiest way to get started. In the default mode, the
KSZ8765 acts as a stand-alone 4 port switch and one RGMII up-link. The user has to simply set the
board’s configuration jumpers to the desired settings and apply power to the board. The user can
also change jumper settings while power is applied to the board and press the convenient manual
reset button for the new settings to take effect. Note that even if there is no external strap in values
are set, internal pull up and pull down resistors will set the KSZ8765 default configuration. Section
4.1.1 covers each jumper on the board and describes its function.
The KSZ8765 will start automatically after power up or reset.

An example for SW5-RGMII with Gigabit port and a processor platform with Gigabit
port evaluation connection:
KSZ8765+9031-EVAL boards are used to connect with a processor board with a PHY/GPHY
for port 5 SW5-RGMII communication, because KSZ9031RNX is a GPHY with RGMII
interface. For using KSZ9031GPHY, the jumpers in Table 5 should be all closed. The jumpers
in Table 6 should be all open. Figure shows below.
KSZ8765+9031 board should be set to SW5-RGMII mode (JP10 and JP9 Open), as KSZ9031RNX is
Gigabit PHY with RGMII interface. The configurations below need to be considered based on the
processor platform.
1. If the processor board with 10/100Mbps PHY port, JP5 of KSZ8765-EVAL board should be
closed for the port 5 SW5-RGMII with 10/100Mbps mode to link up with a 10/100PHY of a
processor platform.
2. If the processor board with GPHY port and want to communicate in 10/100Mbps mode of
10/100/100Mbps, JP5 of KSZ8765-EVAL board should be closed for the port 5 SW5-RGMII
with 10/100Mbps mode to link up with a GPHY of a processor platform.
3. If the processor board with a Gigabit PHY port and want to communicate 1Gbps mode, JP5 of
KSZ8765-EVAL board should be open for the port 5 SW5-RGMII with 1Gbps mode.
4. If port 5 SW5-RGMII is 1Gbps mode with KSZ9031RNX RGMII, the Register 86 (0x56) Bits
[4:3] should be set to ‘11’ (default are ‘01’) with internal delay for both clocks of the ingress
and the egress, because KSZ9031RNX is ‘00’ without internal delay as default for both clocks
of the ingress and the egress.

Some Examples for GMII/RGMII/MII/RMII evaluation connection:
If want by-pass KSZ9031 to test MII/RMII/GMII mode by using the connectors, the jumpers in
table 5 need should be open, the jumpers in table 6 should be closed. There are examples as follows.
1. KSZ8765CLX-EVAL board with KSZ8081MNX/MLX PHY board for MII access.
KSZ8765 can be set to SW5-MII MAC mode, this MAC-PHY connection Figure shows
below.
JP17 Pin 1-2 on KSZ8765CLX-EVAL board needs to be closed for the connector with 3.3V
power that is KSZ8081MNX-EVAL board request.
2.
KSZ8765CLX-EVAL board with KSZ8081RNA/RND PHY board for RMII access.
KSZ8765 can be set to SW5-RMII normal mode with KSZ8081RNA-EVAL board or set to
SW5-RMII clock mode with KSZ8081RND-EVAL board, the Figure shows below.
3.
From the Figure shows above, when KSZ8765-EVAL board connect with KSZ8081 family
PHY evaluation boards for RMII access,
JP17 Pin 2-3 on KSZ8765CLX-EVAL board need to be closed for the connector with 5V
power that is KSZ8081RNA/RND-EVAL board request.
When KSZ8765CLX-EVAL board hooks up with KSZ8081RND board, KSZ8795 should be
set to RMII clock mode.
When KSZ8765CLX-EVAL board hooks up with KSZ8081RNA board, KSZ8795 should be

set to RMII normal mode.
4.
Two KSZ8765CLX-EVAL boards with back to back connection for GMII/RGMII access.
a). One can be set to SW5-GMII MAC mode, another one set to SW5-GMII PHY mode.
b). One can be set to SW5-RGMII with Gbps or Mbps mode, another one set to SW5-RGMII
with Gbps or Mbps mode, the connection Figure shows below.
c). Two KSZ8765CLX-EVAL boards connect together with GMII/RGMII Gigabit mode that
can be used for a non-blocking multiple ports switch, or evaluate for SW5-GMII/RGMII.
In RGMII mode, the RGMII configuration needs to be checked, the register setting is
necessary sometime. Please see a table of RGMII clock delay configuration in SW5-RGMII
Interface section of the datasheet for the setting details.
For example, one board set Register 86 bits [4:3] =’01’ (default), another board must be same
Register 86 bits [4:3] =’01’. If one board set Register 86 bits [4:3] =’10’, another board must be
same Register 86 bits [4:3] =’10’. If one board set Register 86 bits [4:3] =’11’, another board
must be set Register 86 bits [4:3] =’00’ for the correct RGMII configuration.
