USER’S GUIDE

Chapter 1. Overview

1.1 INTRODUCTION

The EVB-KSZ9897 evaluation board features three Gigabit Ethernet products, KSZ9897R, KSZ9031RNX and LAN7801. The KSZ9897R is a seven-port managed gigabit Ethernet switch. It has five 10BASE-Te/100BASE-TX/1000BASE-T physical layer transceivers (PHYs) and associated MAC units, and two MAC ports with individ-ually configurable RGMII/MII/RMII interfaces. These two ports can be used for direct connection to a host Microprocessor or Microcontroller, another Ethernet switch or an Ethernet PHY.

KSZ9031 is a single chip 10/100/1000 Mbps IEEE 802.3 compliant Ethernet PHY. This demonstration board features the RGMII variant, KSZ9031RNX, of the KSZ9031 fam-ily. This feature-rich device offers diagnostic features, such as, LinkMD®, Parametric NAND tree and loopback functions to facilitate system bring-up and debugging in prod-uct testing and deployment. The on-chip termination resistors for the four differential pairs reduce the total board cost.

LAN7801 is a USB 3.1 to 10/100/1000 Gigabit Ethernet bridge with integrated OTP and EEPROM controller. The internal USB controller and USB PHY are compliant with the USB 3.1 Gen 1 SuperSpeed standard that implements Control, Interrupt, Bulk-in, and Bulk-out USB Endpoints. The Ethernet controller is compliant with the IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, and 802.3az (Energy Efficient Ethernet) standards. The device provides multiple power management features, including Energy Efficient Ether-net (IEEE 802.3az), support for Microsoft's Always On Always Connected (AOAC), and “Magic Packet”, “Wake On LAN”, and “Link Status Change” wake events.

An external clock, DSC400, is used on this board to provide very low jitter clock pulses to the KSZ9897, LAN7801 and KSZ9031 Gigabit Ethernet controllers. The DSC400 is a four output crystal-less™ clock generator. It utilizes MEMS technology to provide excellent jitter and stability while providing excellent shock and vibration immunity. The device outputs wide frequency range of 2.3 MHz to 460 MHz with high noise rejection of -50 dbC. The DSC400 provides two independent select lines for choosing between two sets of pre-configured frequencies per bank. It also has two Output Enable pins to allow for enabling and disabling outputs.

On this board, the KSZ9897R Ethernet switch's five ports, 1 through 5, are connected directly to RJ45 Ethernet jacks with integrated magnetics which are available to use with any Ethernet devices. The rest of the two MAC ports are configured as RGMII interfaces. Port 6 is connected to a KSZ9031 Gigabit Ethernet PHY and an RJ45 Ether-net jack with integrated magnetics and port 7 is connected to a LAN7801 USB-to-Ether-net bridge and a USB connector.

The scope of this document is to describe the EVB-KSZ9897 evaluation board setup, which includes RGMII, SPI and I2C interface and corresponding jumper configurations. A simplified block diagram of the board is shown in Figure 1-1.

Chapter 2. Board Details & Configuration

This section includes sub-sections on the following KSZ9897 details:

• Power

• Resets

• Clock

• Configuration

• Mechanicals

2.1 POWER

2.1.1 +5V Power

A 5V/2A power supply should be connected to J7 on the board. The SW2 switch must be in the ON position to power the board. The F1 fuse is provided on the board for the over voltage protection.

2.2 RESETS

2.2.1 Power-on Reset

There are three jumpers, J15, J21 and J23, available for configuring the various reset options for the chips. Unless experimentation with reset is required, it is suggested to use the default configurations highlighted in bold text in the tables below. With these default settings, pressing the SW1 reset button will reset all three devices (KSZ9897, KSZ9031 and LAN7801). By changing the jumpers, the effect of SW1 can be limited to a subset of the three devices.

2.3 CLOCK

The evaluation board utilizes an external clock, DSC400, which provides 25 MHz 25 ppm clock to the KSZ9897, LAN7801 and KSZ9031. It also provides 125 MHz to the LAN7801.



2.4 CONFIGURATION

The following sub-sections describe the various board features and configuration set-tings. A top view of the KSZ9897 is shown in Figure 2-1.

Board Details & Configuration

2.4.1 Switch Settings

SW4 is an eight-position switch which controls many of the KSZ9897 configuration strap options. The KSZ9897 samples these signals at the rising edge of RESET_N to determine some internal settings. Following reset, the configuration of these switches is irrelevant. For initial bring-up, leave most switches in the OFF/OPEN position.

2.4.1.1 KSZ9897 MANAGEMENT INTERFACE MODE

The management interface can be configured to be SPI, I2C or MIIM (a.k.a. MDC/MDIO). This is controlled by switches 1 and 7 of SW4.

Table 2-1 details the switch configuration for the management interface mode.

2.4.1.2 OTHER SWITCH SETTINGS

Please refer the device data sheet for the detailed configuration strap settings.

2.4.2 Jumper Settings

Table 2-2, Table 2-3 and Table 2-4 describe the jumper settings. The preferred config-uration is shown in bold text.

This setting must match the actual link speed of port 6.The KSZ9897 port 6 speed can also be set via the SPI or I2C interface by writ-ing to registers 0x6300 (bit 4) and 0x6301 (bit 6). See the data sheet for details. This method is required when the port 6 link speed is 10 Mbps.

External access to the KSZ9897 (either SPI, I2C or MIIM) is available via header J22 as outlined in Table 2-4. If both connections are needed simultaneously, it will be necessary to remove resistor R95. Please visit Table 2-5 and Table 2-6 for I2C and SPI connections.

Note: Communication formats and register details are provided in the device data sheets. Note that SPI or I2C provide access to all KSZ9897 registers, but MIIM does not. It only provides access to the PHY registers of the switch.



2.5 USING THE EVB-KSZ9897

The EVB-KSZ9897 board can be used to connect up to 7 Ethernet devices using 6 Ethernet ports and 1 USB port.

For example, connect a PC (PC1) on port 1 and another PC (PC2) to port 2. Configure both PCs for STATIC IP address using the Ethernet interface’s properties windows. Then, run a simple PING command to test communication between the two PCs. Lastly, connect PC2 to the USB port, port 7, on the board.

A user can access the KSZ9897 switch's internal registers by connecting Aardvark I2C/SPI host adapter to jumper 22. The adapter is available to purchase from MicrochipDirect.com web site (part number TTP100005).

RGMII layout requirements1. Match trace legths within 100 mils.2. RX signals do not need to be length matched to TX signals.3. Due to KSZ9897 port 6 RGMII setup time requirement, P6_TXC must be routed for additional 1.2ns delay relative to P6_TXD[3:0] and P6_TX_CTL.The amount of required extra delay may differ for different VDDIO voltageor for a different device driving the signals.4. Alternatively, the additional P6_TXC trace delay is not needed if theRGMII ingress delay bit is set in the KSZ9897: bit 4 in register 0x6301.

R49 is reduced to 0 ohms, andinstalled at R89 to improve P6time at KSZ9897 relative to P

Reason: P6_TXC is routed 5 ithe other P6_TX signals on thadded delay is insufficient.
