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.
