USER’S GUIDE  2017 Microchip Technology Inc. DS50002594A-page 11 Chapter 1. Overview

1.1 INTRODUCTION

The EVB-KSZ9477 evaluation board features the KSZ9477 seven-port managed giga- bit 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 pro- vides 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.

USER’S GUIDE  2017 Microchip Technology Inc. DS50002594A-page 15 Chapter 2. Board Details & Configuration This section includes sub-sections on the following EVB-KSZ9477 details:

• P o w e r
• Resets
• Clocks
• Configuration
• Mechanicals

2.1 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.

2.4 CONFIGURATION

The following sub-sections describe the various board features and configuration set- tings. A top view of the EVB-KSZ9477 is shown in Figure 2-1. FIGURE 2-1: EVB-KSZ9477 TO P VIEW WITH CALLOUTS

Board Details & Configuration  2017 Microchip Technology Inc. DS50002594A-page 17

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 configura- tion is shown in bold text. TABLE 2-1: TWO-PIN JUMPERS Jumper Label Description Open Closed J6 P6 100 Mbps KSZ9477 Port 6 configured for RGMII. This interface is connected to the SAMA5D36 MPU.
