Page 5 5/2/2014 KSZ8895 Evaluation Board User’s Guide 4.0 Hardware Description The KSZ8895 evaluation board is in a compact form factor and can sit on a bench near a computer with USB connector. There are four options for configuration: strap in mode; EEPROM mode, SMI mode and SPI mode. Strap in mode configuration is easily done with on board jumper options. EEPROM mode, SMI mode and SPI mode are accomplished through a built in USB port interface. Using Micrel EEPROM software and your PC, you can program the EEPROM on board by the USB port. Using Micrel SPI software and your PC, you can access the KSZ8895’s full feature set registers by the USB to SPI interface. Or using Micrel MDC/MDIO software and SMI software with your PC, you can access the KSZ8895’s MIIM PHY registers by generic MDC/MDIO interface and full feature set registers by the SMI mode of MDC/MDIO interface. The board also features the MII connectors for the Switch MII/RMII interface. These are to facilitate connections from the switch to an external MAC or PHY. There is also an additional MII connector for the PHY5 MII/RMII interface to an external MAC. This is used to recover use of the fifth PHY unit in broadband gateway applications or others. The KSZ8895 evaluation 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 JP47 jumper.

In this mode, the KSZ8895 acts as a stand-alone 5 port switch. 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 KSZ8895 default configuration. Section 4.1.1 covers each jumper on the board and describes its function. To start in strap in configuration mode, make sure that JP1 and JP2 are closed and JP3, JP4, JP8 and JP9 are open. In this mode, pins (PS1,PS0)=(0,0), the chip will start automatically, after trying to Micrel Inc. Page 7 5/2/2014 KSZ8895 Evaluation Board User’s Guide read the external EEPROM, if EEPROM does not exist, the chip will use the default values and the strap option setting for all internal registers. 4.1.1 Feature Setting Jumpers The evaluation board provides jumpers to allow the user to easily set strap in configurations for the KSZ8895.

The ports J1, J2, J3, J4 and J5 are the standard RJ45 connectors and using CAT-5 cables. Each port can be used as either an uplink or downlink. All ports support auto MDI/MDIX so there is no need for cross over cables. J1 = RJ45 connector for port 1 J2 = RJ45 connector for port 2 J3 = RJ45 connector for port 3 J4 = RJ45 connector for port 4 J5 = RJ45 connector for port 5 Micrel Inc. Page 11 5/2/2014 KSZ8895 Evaluation Board User’s Guide 4.5 LED indicators Ethernet Port LEDs There are five columns of LED indicators on the board, one column for each of the five ports. The LED indicators are programmable to two different modes. You can program the LED mode through a strap in option on JP23 or in register 11, bit 1. The mode definitions are shown in Table 5. There are three LEDs per port. The naming convention is “LEDx_y”, where “x” is the port number, and “y” is the number of the LED for that port. Table 5 LED Modes Mode 0 LEDx_2 = Link/Act LEDx_1 = Full Duplex/Col LEDx_0 = Speed Mode1 LEDx_2 = 100Link/Act LEDx_1 = 10Link/Act LEDx_0 = Full Duplex LED1_y are assigned to Port1. LED2_y are assigned to Port2. LED3_y are assigned to Port3. LED4_y are assigned to Port4. LED5_y are assigned to Port5. Power LED The board also has a power LED D3 for the 3.3V power supply. D3 LED indicates 3.3V Power on and off. Interrupt LED The board also has an Interrupt LED D2 for the Link status change when set the interrupt mask register 125. D2 LED is turn on to indicate the interrupt to be asserted. 4.6 MII/RMII Ports Configuration There are two MII/RMII ports on the KSZ8895. One port connects to the fifth MAC in the KSZ8895, and we refer to it as the port 5 Switch SW5-MII/RMII port. The second MII port connects to the fifth PHY in the KSZ8895. We refer to this as the PHY5 P5-MII/RMII port. Both the Switch MII/RMII port and the PHY5 MII/RMII port configuration are set on the board by using the MII Enable bit (register 2, bit 3) in conjunction with JP10 and JP11 as shown in Table 6. The Switch MII/RMII port can be set to PHY mode, MAC mode or SNI mode. In PHY mode, the Switch MII/RMII port will transmit and receive signals on J6 of the board’s male MII connector. This mode is usually used to connect the KSZ8895 to a CPU with MAC. In MAC mode, the Switch MII/RMII port will transmit and receive signals on J7 of the board’s female MII connector. This Micrel Inc. Page 12 5/2/2014 KSZ8895 Evaluation Board User’s Guide interface is normally used to connect the KS8895 to an external PHY. We also have provisions on the board to support the SNI 7 wire interface. In SNI mode, the Switch MII port will transmit and receive signals on header pins. The connections between the header pins and the SNI signals are shown in the Table 7. The PHY5 MII/RMII port is used to connect to an external MAC or CPU. This port is only in PHY mode.
