EVB-KSZ9477 Gigabit Ethernet Switch Evaluation Board User's Guide 2017 Microchip Technology Inc. DS50002594A Note the following details of the code protection feature on Microchip devices: * Microchip products meet the specification contained in their particular Microchip Data Sheet. * Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. * There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip's Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. * Microchip is willing to work with the customer who is concerned about the integrity of their code. * Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as "unbreakable." Code protection is constantly evolving.

DS50002594A-page 10 2017 Microchip Technology Inc. EVB-KSZ9477 EVALUATION BOARD USER'S GUIDE Chapter 1. Overview 1.1 INTRODUCTION The EVB-KSZ9477 evaluation board features the KSZ9477 seven-port managed gigabit Ethernet switch. It has five 10BASE-Te/100BASE-TX/1000BASE-T physical layer transceivers (PHYs) and associated MAC units, one SGMII and one RGMII interfaces. Ports 1 through 5, with integrated MAC and PHY are connected to RJ45 Ethernet jacks with integrated magnetics. The SGMII interface is connected to a small form-factor pluggable (SFP) transceiver receptacle whereas, the RGMII interface is connected to the SAMA5D36A embedded microprocessor (MPU). A user can use the on-board MPU for the customized applications such as IEEE 1588, audio-video bridging (AVB) and ring redundancy (DLR & HSR). The board also provides 2Gb (265MB) DDR2 SDRAM and 2Gb (256MB) of NAND flash memory. The scope of this document is to describe the EVB-KSZ9477 evaluation board setup and corresponding jumper configurations. A simplified block diagram of the board is shown in Figure 1-1. 2017 Microchip Technology Inc. DS50002594A-page 11 EVB-KSZ9477 Evaluation Board User's Guide FIGURE 1-1: 1.2 EVB-KSZ9477 BLOCK DIAGRAM REFERENCES Concepts and material available in the following documents will be helpful when reading this document.

Board Details & Configuration This section includes sub-sections on the following EVB-KSZ9477 details: * * * * * 2.1 Power Resets Clocks Configuration Mechanicals POWER 2.1.1 +5V Power A 5V/2A power supply should be connected to J8 on the board. The SW4 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 two push button switches, SW1 and SW3 available on board. The SW1 switch is a master reset which resets both the MPU and the KSZ9477 Ethernet switch. SW3 resets only the KSZ9477. 2.3 CLOCKS The evaluation board utilizes a crystal oscillator that provides 25 MHz clock to the KSZ9477 device. The board also features an external clock, DCS1101, which provides 125 MHz 25 ppm clock to the MCU device in the SGMII mode. 2017 Microchip Technology Inc. DS50002594A-page 15 EVB-KSZ9477 Evaluation Board User's Guide 2.4 CONFIGURATION The following sub-sections describe the various board features and configuration settings. A top view of the EVB-KSZ9477 is shown in Figure 2-1. FIGURE 2-1: DS50002594A-page 16 EVB-KSZ9477 TOP VIEW WITH CALLOUTS 2017 Microchip Technology Inc. Board Details & Configuration 2.4.1 Switch Settings SW2 is an eight-position switch which controls many of the KSZ9477 configuration strap options. The KSZ9477 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. 2.4.2 Jumper Settings Table 2-1, Table 2-2 and Table 2-3 describe jumper settings. The preferred configuration is shown in bold text.

Therefore DDR2 devices have to be placed as close as possible to SAMA5D3. The layout EBI DDR2 should use controlled impedance traces of Z0= 50ohm. Address, control and data traces may not exceed 1.3 inches (33mm). Address, control and data traces must be length matched to within 0.1 inch (2.54mm). Address, control and data traces must match the data group trace lengths to within 0.25 inch (6.35mm).
