AM2x Evaluation Module for Industrial Ethernet PHY Add-
on Board
Description
DP83826-EVM-AM2 is an Industrial Ethernet PHY
add-on board to be used with AM2x series Sitara
high-performance microcontroller evaluation modules.
This add-on board is an excellent choice for initial
Ethernet evaluation and prototyping using AM2x
EVMs. DP83826-EVM-AM2 is equipped with a TI
DP83826 low latency 10/100-Mbps PHY with MII
interface and enhanced mode, and a standard RJ45
Ethernet networking connector. DP83826-EVM-AM2
is currently supported on
AM263Px MCU PLUS
SDK.

These resistors are not assembled by default on the DP83826-EVM-AM2, but there are footprints if the main EVM does not have these signals pulled up. The interrupt signal is driven by a GPIO signal that is mapped from the main EVM SoC.
