DS50002587A-page 10 2017 Microchip Technology Inc. EVB-KSZ9897 EVALUATION BOARD 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 individually 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 family. This feature-rich device offers diagnostic features, such as, LinkMD(R), Parametric NAND tree and loopback functions to facilitate system bring-up and debugging in product 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 Ethernet (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-lessTM 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 Ethernet jack with integrated magnetics and port 7 is connected to a LAN7801 USB-to-Ethernet 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. 2017 Microchip Technology Inc.

Board Details & Configuration This section includes sub-sections on the following KSZ9897 details: * * * * * 2.1 Power Resets Clock Configuration Mechanicals 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. 2017 Microchip Technology Inc.

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 voltage or for a different device driving the signals. 4. Alternatively, the additional P6_TXC trace delay is not needed if the RGMII ingress delay bit is set in the KSZ9897: bit 4 in register 0x6301. 4 R81 1k D6 Br Red 74LVC1G14GW,125 R93 2.05k R94 10k SPI / Aardvark DNP DNP R126 R127 R128 0R I2C_SCL 1 0R I2C_SDA 3 5 0R SP_CLK 7 9 J22 2 4 6 8 10 SP_MOSI R129 0R SDA/MDIO 3V3_Board C31 0.1uF 2, 4, 5 PHY_RESET_N_OUT 4, 5 2 VCC C U2 4 R96 GND D 9897 Reset Select 127 ISET R106 SW_RESET_N 1-2 Reset from Push Button 2-3 Reset from LAN7801 Place Reset ckt close to 9897 C167 "SW Reset" U14 Header 5x2 Shrouded PHY_INT_N 5 R102 DNP 0R 95 R92 10k VDDIO2v5 1k R39 J23 1 1 VCC C VDDIO2v5 SDA/MDIO MISO 125 XO 126 XI VDDIO2v5 1k Prt 7: LAN7801 SW4 16 15 14 13 12 11 10 9 10uF 6.3V GND D 2 R83 2, 4, 5 C73 2 PME_N PHY_INT_N KSZ_RESET_N 6.04k 1% 1 2 3 4 5 6 7 8 SW_RESET_N 3 4 Prt 6: KSZ9031 P6_RXC 4 P6_RX_CTL 4 66 69 67 68 70 71 72 73 75 76 78 4 4 4 4 5 P6_RXC_R P6_RX_CTL_R R108 1k LED2_0 P6_TXD3 P6_TXD2 P6_TXD1 P6_TXD0 VDDIO2v5 2 LED4_0 LED4_1 KSZ9897R LED3_1 PME_N INTRP_N RESET_N 60 62 63 64 65 4 3 CRS6 RXD6_3 RXD6_2 RXD6_1 RXD6_0 57 58 59 P6_TX_CTL SW1 RX_CLK6/REFCLKO6 RX_DV6/CRS_DV6/RX_CTL6 RX_ER6 TXRX2P_A TXRX2M_A TXRX2P_B TXRX2M_B TXRX2P_C TXRX2M_C TXRX2P_D TXRX2M_D 4 5 P3_TXRXA_P P3_TXRXA_N P3_TXRXB_P P3_TXRXB_N P3_TXRXC_P P3_TXRXC_N P3_TXRXD_P P3_TXRXD_N LED1_0 LED1_1 P6_TXC 3 LED2_0 LED2_1 3 3 3 3 3 3 3 3 105 106 12 13 15 16 17 18 20 21 LED2_0 LED2_1 3 3 3 3 3 3 LED1_0 LED1_1 48 51 49 50 52 53 54 55 1 2 P2_TXRXA_P P2_TXRXA_N P2_TXRXB_P P2_TXRXB_N P2_TXRXC_P P2_TXRXC_N P2_TXRXD_P P2_TXRXD_N TX_CLK6/REFCLKI6 COL6 TX_EN6/TX_CTL6 TX_ER6 TXD6_3 TXD6_2 TXD6_1 TXD6_0 1 LED1_0 LED1_1 3 3 3 3 3 3 3 3 TXRX1P_A TXRX1M_A TXRX1P_B TXRX1M_B TXRX1P_C TXRX1M_C TXRX1P_D TXRX1M_D CONTROL 3 3 1 2 4 5 6 7 8 9 SPI P1_TXRXA_P P1_TXRXA_N P1_TXRXB_P P1_TXRXB_N P1_TXRXC_P P1_TXRXC_N P1_TXRXD_P P1_TXRXD_N CLK 3 3 3 3 3 3 3 3 MII/RMII/RGMII DS50002587A-page 22 FIGURE B-1: 74LVC1G14GW,125 "9897 SPI Activity" D3 1k Blue RJ45 MAGJACK CONNECTORS PORT 1 J2 2 LED1_0 2 P1_TXRXA_P 2 2 P1_TXRXA_N P1_TXRXB_P 2 2 P1_TXRXB_N P1_TXRXC_P 2 2 P1_TXRXC_N P1_TXRXD_P 2 P1_TXRXD_N 13 LED1_0 GC1 GA1 PORT 4 J1 VDDIO2v5 VDDIO2v5 GREEN (LINK/ACT) 14 GREEN (LINK/ACT) R2 2 LED4_0 2 P4_TXRXA_P 2 2 P4_TXRXA_N P4_TXRXB_P 2 2 P4_TXRXB_N P4_TXRXC_P 2 2 P4_TXRXC_N P4_TXRXD_P 2 P4_TXRXD_N 13 LED4_0 GC1 GA1 14 100R 100R C2 C4 C6 C8 11 0.1uF 12 10 4 0.1uF 6 5 3 0.1uF 1 2 8 0.1uF 7 9 TRD1+ TRCT1 TRD1TRD2+ TRCT2 TRD2TRD3+ TRCT3 TRD3TRD4+ TRCT4 TRD4- Power i EARTH_ETH SHIELD1 2 LED1_1 LED1_1 15 C95 GC2 GA2 16 C1 C3 C5 1000 pF 2 kV 0 C7 11 0.1uF 12 10 4 0.1uF 6 5 3 0.1uF 1 2 8 0.1uF 7 9 R4 EARTH_ETH SHIELD1 2 LED4_1 15 LED4_1 GC2 GA2 0 16 VDDIO2v5 R3 100R GREEN (Duplex/Collision) RJ45 Magjack RJ45 Magjack PORT 2 J3 TRD1+ TRCT1 TRD1TRD2+ TRCT2 TRD2TRD3+ TRCT3 TRD3TRD4+ TRCT4 TRD4- VDDIO2v5 100R GREEN (Duplex/Collision) R1 PORT 5 J4 VDDIO2v5 GREEN (LINK/ACT) 2 LED2_0 2 P2_TXRXA_P 2 2 P2_TXRXA_N P2_TXRXB_P 2 2 P2_TXRXB_N P2_TXRXC_P 2 2 P2_TXRXC_N P2_TXRXD_P 2 P2_TXRXD_N 13 LED2_0 GC1 GA1 14 VDDIO2v5 GREEN (LINK/ACT) R5 2 LED5_0 2 P5_TXRXA_P 2 2 P5_TXRXA_N P5_TXRXB_P 2 2 P5_TXRXB_N P5_TXRXC_P 2 2 P5_TXRXC_N P5_TXRXD_P 2 P5_TXRXD_N 13 LED5_0 GC1 GA1 14 100R 11 0.1uF 12 10 4 C11 0.1uF 6 5 3 C13 0.1uF 1 2 8 C15 0.1uF 7 9 C9 TRD1+ TRCT1 TRD1TRD2+ TRCT2 TRD2TRD3+ TRCT3 TRD3TRD4+ TRCT4 TRD4- 2 LED2_1 LED2_1 15 GC2 GA2 0 16 2 PORT 3 VDDIO2v5 2 P3_TXRXA_P LED3_0 13 GC1 GA1 14 R9 100R DS50002587A-page 23 2 2 P3_TXRXA_N P3_TXRXB_P 2 2 P3_TXRXB_N P3_TXRXC_P 2 2 P3_TXRXC_N P3_TXRXD_P 2 P3_TXRXD_N 11 C22 0.1uF 12 10 4 C23 0.1uF 6 5 3 C24 0.1uF 1 2 8 C25 0.1uF 7 9 TRD1+ TRCT1 TRD1TRD2+ TRCT2 TRD2TRD3+ TRCT3 TRD3TRD4+ TRCT4 TRD4- EARTH_ETH SHIELD1 2 LED3_1 LED3_1 15 GC2 GA2 GREEN (Duplex/Collision) RJ45 Magjack LED5_1 LED5_1 15 GC2 0 16 VDDIO2v5 R15 100R GA2 GREEN (Duplex/Collision) RJ45 Magjack GREEN (LINK/ACT) LED3_0 EARTH_ETH SHIELD1 R7 RJ45 Magjack 2 10 4 6 5 3 C14 0.1uF 1 2 8 C16 0.1uF 7 9 C12 0.1uF TRD1+ TRCT1 TRD1TRD2+ TRCT2 TRD2TRD3+ TRCT3 TRD3TRD4+ TRCT4 TRD4- VDDIO2v5 100R GREEN (Duplex/Collision) J5 100R 11 C10 0.1uF 12 EARTH_ETH SHIELD1 R6 0 16 VDDIO2v5 R8 100R EVB-KSZ9897 Evaluation Board Schematics 2017 Microchip Technology Inc.
