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.”

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.

Chapter 2. Board Details & Configuration
This section includes sub-sections on the following EVB-KSZ9477 details:
•Power
• 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.

DS50002594A-page 16 2017 Microchip Technology Inc.
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.

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
Tab le 2 -1 , Ta ble 2 -2 and Tab le 2- 3 describe jumper settings. The preferred configura-
tion is shown in bold text.

Keep nets as short as possible. 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).

RGMII layout requirements
1. Match lengths within 50 to 100 mils.
2. RX signals do not need to be length matched to TX signals.
3. Due to RGMII timing error in port 6 of KSZ9477, plus
SAMA5D36 compliance to RGMII v1.3, GTXCK must be
routed for additional 2.0 ns delay relative to GTXD[3:0] and
GTXCTL.
