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. We at Microchip are committed to continuously improving the code protection features of ourproducts. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such actsallow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

Chapter 1. Overview

1.1 INTRODUCTION

The EVB-KSZ9893 evaluation board is a plug-in card that interfaces directly with a mat-ing Microchip host processor or controller board, such as the SAMA5D3 EthernetDevelopment System (EDS) board. It features the KSZ9893, a highly integrated net-working device that incorporates a layer-2+ managed Gigabit Ethernet switch, two10BASE-T/100BASE-TX/ 1000BASE-T physical layer transceivers (PHYs) and asso-ciated MAC units, and one MAC port configured as the RGMII interface. The board’stwo PHY ports are connected to RJ45 Ethernet jacks with integrated magnetics, andthe RGMII MAC interface is brought out to a high-speed multi-pin (HS) connector.

Together, the EVB-KSZ9893 and the SAMA5D3-EDS provide a highly-flexible platformfor evaluation of basic PHY/Switch features via static Control-Status Registers (CSRs)and development of firmware for advanced MAC/Switch features that require interac-tion with upper network layers (for example, IEEE1588 PTP, AVB, and RSTP/MSTP).

The scope of this document is meant to describe the EVB-KSZ9893 setup and its userinterface features. A simplified block diagram of the board is shown in Figure 1-1.

USER’S GUIDE

Chapter 2. Getting Started

2.1 INTRODUCTION

The EVB-KSZ9893 evaluation board is designed as a plug-in card to interface directlywith a mating Microchip host processor or controller board, such as theSAMA5D3-EDS Board, that supplies full power and provides full register access andconfiguration via In-Band Management Access (IBA), SPI, or I2C bus management.

2.2 POWER SOURCE

The EVB-KSZ9893 is completely bus-powered from its mating Microchip host proces-sor or controller board. Input power is delivered via the high-speed multi-pin (HS) con-nector.

Refer to Figure 2-3 and board schematics in Appendix B. “Schematics” for details.

2.2.1 Power Probe Points

The power probe points along with the ground test points are shown in Figure 2-2.

2.2.2 Current Access Rework/Probe Points

The EVB-KSZ9893 design is not intended to perform current measurements on the device. If needed, the current access points to measure the current consumptions of the KSZ9893 power rails are across the following series ferrite beads to the board pow-ers.

• DVDDL: FB2

• AVDDL: FB3

• VDDIO: FB6

• AVDDH: FB4 for 3.3V (default populate) and FB1 for 2.5V (default not populate)

Remove the above ferrite beads and place the current probes in series across the power probe points (Section 2.2.1 “Power Probe Points”) that are joined by the fer-rite beads. See also Appendix B. “Schematics”.

Board LED components are connected to the VDDIO power rail, and thus the mea-sured current is higher than the amount consumed by only the KSZ9893 device.

2.3 CLOCK

The EVB-KSZ9893 utilizes a 25 MHz crystal to generate the input reference clock forthe KSZ9893 device. Refer to Figure 2-1 and the board schematics in AppendixB. “Schematics” for details.

Note: Populate either FB4 only or FB1 only. If 2.5V AVDDH is desired, FB4 should be “Do Not Populate (DNP)” and FB1 should be populated.



2.4 RESET

2.4.1 Power-On Reset

The discrete RC/Diode (R12, C8, and D3) circuit provides power-on reset to the KSZ9893 device.

2.4.2 Manual Reset

The SW1 reset button can be pressed and released to provide manual reset to the KSZ9893 device after power-up. Refer to Figure 2-1 and the board schematics in Appendix B. “Schematics” for details.

2.5 BOARD FEATURES AND CONFIGURATION

The following sub-sections describe the board features and configuration settings.

Figure 2-1 displays the top view of the EVB-KSZ9893 with key features, jumpers, and headers which are highlighted in red. The Microchip components are highlighted in blue.

2.5.1 PHY Ports – Integrated Magnetic Jacks

PHY ports 1 and 2 (J2 and J6) support 10BASE-T/100BASE-TX/1000BASE-T withboth Auto-negotiation enabled and Auto-MDI/MDI-X enabled as the power-up defaults.

2.5.2 PHY Ports – LEDs

Two Dual-LEDs (D2 and D6) provide the link status for PHY ports 1 and 2, respectively. The LED descriptions are listed in Table 2-1.

2.5.3 Pin Strapping Configuration

As the power-up or reset defaults, the KSZ9893 device is configured via internal or external pull-up or pull-down resistors to the following settings:

• PHY Ports 1 and 2: Auto-negotiation enabled and Energy-Efficient Ethernet (EEE) enabled

• MAC Port 3: RGMII mode at 1000 Mbps speed

• Start Switch: The switch forwards packets immediately after hardware reset.

• Management: SPI Slave mode

Getting Started

The IBA mode and Quiet-Wire® pin strappings can be enabled or disabled using the 3-pin jumpers in Table 2-2. Set the desired jumper settings prior to board power-up, hardware reset, or both.

Refer to the board schematics in Appendix B. “Schematics” and the KSZ9893 Data Sheet for further details on the pin strappings.

2.5.4 GPIO Signal Headers

Table 2-3 shows the GPIO signals that support the IEEE 1588 Precision Time Protocol (PTP).

Refer to the board schematics in Appendix B. “Schematics” and the KSZ9893 Data Sheet for further details and usage on the GPIO signal pins.

2.5.5 INTRP_N Output

The INTRP_N output at test point TP14 provides the interrupt output from the KSZ9893 device. By default, it is active low and drives low to turn on D4 when asserted.

Refer to the board schematics in Appendix B. “Schematics” and the KSZ9893 Data Sheet for further details and usage on the INTRP_N signal.

2.5.6 PME_N Output

The PME_N output at test point TP16 provides the Power Management Event (PME) interrupt output for Wake-on-LAN (WoL) from the KSZ9893 device. By default, it is active low and drives low to turn on D5 when asserted.

Refer to the board schematics in Appendix B. “Schematics” and the KSZ9893 Data Sheet for further details and usage on the PME_N signal.

2.6 USING THE EVB-KSZ9893

The EVB-KSZ9893 directly plugs into a mating Microchip host controller or processorboard, such as the SAMA5D3-EDS Board, that delivers full power and provides full reg-ister access and configuration via IBA, SPI, or I2C bus management.

Together, the EVB-KSZ9893 and the SAMA5D3-EDS enable 10/100/1000-MbpsEthernet traffic switching across all three data ports of the KSZ9893 device, with RGMIIMAC Port 3 connecting to the SAMA5D3 processor and PHY Port 1 and Port 2 con-necting via copper Ethernet cable (CAT-5 UTP or better) to external Ethernet devices.

All KSZ9893 registers are accessible via IBA, SPI, or I2C bus management from theSAMA5D3-EDS Board, enabling full evaluation and firmware development for allKSZ9893 MAC/Switch features and interaction with upper network layers.

Refer to the SAMA5D3-EDS Board documentation on its usage.

Figure 2-4 shows the EVB-KSZ9893 connected to the SAMA5D3-EDS Board.
