Hi all
I am using CPU TM4C129 TQFP128 Package with MAC PHY built in.When I activate the ETHERNET It causes noises at the VDD.The noises can't be seen by a scope but they can be heared by a speaker as a periodic "tick" noises.
I like to know what is the specific VDD pin that supplies power to the Ethernet PHY so I can filter it ?
