Migrating from the LAN9117 to the LAN9211
The purpose of this application note is to assist Microchip customers with existing LAN9117 designs when upgrading to the new LAN9211 devices. Migrating from the LAN9117 to the LAN9211 will require PCB modifications to support the
new LAN9211 package type and the HP Auto-MDIX PHY (even if this mode is not used). This application note addresses all the differences between the LAN9117 and the LAN9211 devices, making this transition as easy as possible.
