January 11, 20111.0 IntroductionThe KSZ8873MLL/FLL/RLL is Micrel’s third generation fully integrated 3-port switch. The two PHY units of KSZ8873MLL/RLL support 10BASE-T and 100BASE-TX. The KSZ8873FLL supports 100BASE-FX. The devices have been designed for cost sensitive systems, however, still offer a multitude of features, such as switch management, port and tag based VLAN, QoS priority, one MII interfaces and CPU control and data interfaces.The KSZ8873MLL/FLL/RLL is an excellent choice for VoIP Phone, Set-top/Game Box, SOHO Residential Gateway, industrial Ethernet systems and as a standalone 3-port switch.The KSZ8873MLL/FLL/RLL Evaluation Board provides a convenient means to evaluate the KSZ8873MLL/FLL/RLL’s rich feature set. Easy access is provided to all of the KSZ8873MLL/FLL/RLL pins, with jumpers and interface connectors allowing quick configuration and re-configuration of the board. MIIM, EEPROM programming, SPI emulation software are also provided to access the more extensive features of the KSZ8873MLL/FLL/RLL, via a PC USB port.2.0 Board Features•Micrel’s KSZ8873MLL/FLL/RLL Integrated 3-Port 10/100 Managed Ethernet Switch•Two RJ-45 Jacks for Ethernet LAN Interfaces with corresponding Isolation Magnetics (KSZ8873MLL/RLL)•Auto MDI/MDI-X on the PHY port• 1 PHY Mode and 1 MAC Mode MII Connectors for the Switch RMII/MII Interface• 2 100Base-FX fiber interface(KSZ8873FLL)• 1 USB port to emulate an MIIM, EEPROM, SPI Interface•On board EEPROM• 2 LEDs per port to Indicate the Status and Activity of the RJ45 port• 1 power jack for 5VDC Universal Power Supply3.0 Evaluation Kit ContentsThe KSZ8873MLL/FLL/RLL Evaluation kit includes the following:•KSZ8873MLL/FLL/RLL Evaluation Board Revision 1.0•KSZ8873MLL/FLL/RLL Evaluation Board User’s Guide•Micrel Switch Configuration Software Version 1.0.5•Micrel Switch Configuration Software User Guide•KSZ8873MLL/FLL/RLL Evaluation Board Schematic Revision 1.0(Contact your Micrel FAE for the latest schematic)Note: USB cable and 5V DC Wall Power Supply is not included in the design kit (the dimension of the output plug of 5V DC wall power supply is 2.5x5.5x9.5mm or 0.1x0.218x0.375inch)4.0 Hardware DescriptionThe KSZ8873MLL/FLL/RLL Evaluation Board is in a compact form factor and can sit on a bench near a computer. There are three options for configuration: strap in mode, EEPROM mode, and SPI mode. Strap in mode configuration is easily done with on board jumper options. EEPROM mode and SPI mode are accomplished through a built in USB port interface. With the Micrel software and your PC, you can use the USB port to reprogram the EEPROM on board, or use the SPI interface to access the KSZ8873MLL/FLL/RLL’s full feature set. The board also features oneMicrel, Inc. January 11, 2011MII connector for the Switch MII interface. It is to facilitate connection from the switch to either the external CPU or the external PHY.Figure 1: KSZ8873MLL/FLL/RLL Evaluation Board Block DiagramThe KSZ8873MLL/FLL/RLL evaluation board is easy to use. There are programmable LED indicators for link and activity on the PHY ports and a power LED. A manual reset button allows the user to reset the board without removing the power plug. The 5V power on the board can be supplied by a standard 5VDC power supply (close pin 1-2 of JP400 jumper) or by the USB cable (close pin 2-3 of JP400 jumper) which is used to access the registers in SPI mode. A standard 5VDC power supply is included so that the user can supply power from any 110 Volt AC wall or bench socket. Before to start to use the evaluation board, make sure the power connectors JP403, JP404, JP405 and JP31 are connected, and close pin 1-2 of J14.4.1 Strap In ModeStrap in configuration mode is the quickest and easiest way to get started. In this mode, the KSZ8873MLL/FLL/RLL acts as a standalone 3-port switch. Simply set the board’s configuration jumpers to the desired settings and apply power to the board. The configuration can be changed while power is applied to the board by changing the jumper settings and pressing the convenient manual reset button for the new settings to take effect. Note that even if no external strap in values are set, internal pull up and pull down resistors will set the KSZ8873MLL/FLL/RLL 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 the USB cable is unplugged, JP34, JP35, JP3and JP9 are connected, JP21, JP25 have jumpers fitted between pins 2 to 3.Micrel, Inc. January 11, 20114.1.1 Feature Setting JumpersThe evaluation board provides jumpers to allow easy setting of strap in configurations for the KSZ8873MLL/FLL/RLL.

The ports can be connected to an Ethernet traffic generator or analyzer via standard RJ-45 connectors using CAT-5 cables. Each port can be used as either an uplink or downlink. Both ports support auto MDI/MDI-X, eliminating the need for cross over cables.4.5 100FX Fiber Port (KSZ8873FLL)There are two 100FX PHY ports on the KSZ8873FLL evaluation board. The ports can be connected to an Ethernet traffic generator or analyzer via fiber transceiver and fiber cable. The fiber signal threshold can be set by register 192 bit 6(Port1) and bit 7(Port2). If the bits are 1, the threshold will be set to 2.0V, Otherwise it is 1.25V.The resister R76 also need to be adjusted if the FXSD signal value from the fiber module doesn’t meet the fiber signal threshold spec.4.6 LED IndicatorsThere is one column of LED indicator for one column for port 2. The LED indicators are programmable to three different modes. LED mode is selected through register 195 bit [5:4] setting. The LED mode definitions are specified in Table 5. See Figure 1 for the LEDs’ orientation on the KSZ8873MLL/FLL/RLL evaluation board.Table 5: LED ModesRegister 195 Bit[5:4]00 01 10 11PxLED1 = Speed PxLED1 = Active PxLED1 = Duplex PxLED1 = Duplex PxLED0 = Link/Active PxLED0 = Link PxLED0 = Link/Active PxLED0 = LinkThe KSZ8873MLL/FLL/RLL evaluation board provides two LEDs (PxLED1, PxLED0) for each PHY port.The KSZ8873MLL/FLL/RLL evaluation board also has a power LED (D3) for the 3.3V power supply. When D3 is lit, the board’s 3.3V power supply is “on”.4.7 MII Port Configuration (KSZ8873MLL/FLL)The evaluation board provides access to the KSZ8873MML’s MAC via the MII port interfaces. The MAC can be configured to MII PHY mode and MII MAC mode. To configure the MAC, the board’s jumpers JP27 is set as specified in Table 6.Micrel, Inc. January 11, 2011Micrel, Inc. January 11, 2011Table 6: MII Mode SettingsMII Mode MII PHY mode MII PHY mode JP27 for Port 1Pins 1-2 closedPins 2-3 closedIn MII PHY mode, the MII transmit and receive signals will be on J3, the male MII port connectors. This mode is usually used to connect the KSZ8873MML to an external MAC processor. In MII MAC mode, the MII transmit and receive signals will be on J4, the female MII port connector. This interface is normally used to connect the KSZ8873MML to an external PHY, for example the Micrel KSZ8041NL.4.8 RMII Port Configuration (KSZ8873RLL)In RMII interface, the 50MHz reference clock can be provide by the KSZ8873RLL or by the link partner. When pin 1-2 of JP28 is closed, the reference clock will be output from REFCLKO on KSZ8873RLL. Register 198 bit[3] is used to select internal or external reference clock for the KSZ8873RLL RMII interface. If pin 2-3 of JP28 is closed, the REFCLKO disable.Table 7: RMII Clock Setting5.0 Reference DocumentsKSZ8873MLL/FLL/RLL Datasheet Rev. 1.1 (Contact Micrel for latest Datasheet)KSZ8873MLL/FLL/RLL Evaluation Board Schematic Rev. 1.0 (Contact Micrel for latest Schematic)KSZ8873MLL/FLL/RLL Evaluation Board Gerber files Micrel Switch Configuration Software User GuideReg198[3] EN_REFCLKO_3 Clock Source NoteExternal 50MHz OSC input to REFCLKI_3EN_REFCLKO_3 = 0 to DisableREFCLKO_3 for better EMI0 1REFCLKO_3 Output Is Feedback to REFCLKI_3 EN_REFCLKO_3 = 1 to Enable REFCLKO_3 1 1Internal Clock SourceREFCLKI_3 is unconnected EN_REFCLKO_3 = 1 to Enable REFCLKO_3 1 0Not suggest。
