Chapter 2. Board Details and Configuration
2.1
INTRODUCTION
The EVB-KSZ8563 is designed as a plug-in card to interface directly with a mating
Microchip host processor or controller board, such as the SAMA5D3-EDS Board, that
supplies full power and provides full register access and configuration via IBA, SPI, or
I
2
C bus management.
2.2
POWER SOURCE
The EVB-KSZ8563 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
and board schematics in
Appendix B. “EVB-KSZ8563 Schemat-
for details.
2.2.1
Power Probe Points
The power probe points along with the ground test points are shown in
2.2.2
Current Access Rework/Probe Points
The EVB-KSZ8563 design is not intended to perform current measurements on the
device. If needed, the current access points to measure the current consumption of the
KSZ8563 power rails are across the following series ferrite beads to the board powers.
• DVDDL: FB2
• AVDDL: FB3
• VDDIO: FB6
• AVDDH: FB4 for 3.3V (default populate); FB1 for 2.5V (default not populate)
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.
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-
Appendix B. “EVB-KSZ8563 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 KSZ8563 device.
2.3
CLOCK
The EVB-KSZ8563 utilizes the on-board Microchip DSC1001CI2-025.0000 clock chip,
a 25-MHz MEMS oscillator, as the input reference clock to the KSZ8563 device. Refer
to
and board schematics in
Appendix B. “EVB-KSZ8563 Schematics”
for
details.
