I am currently designing a new board with the I210-AT.
Can I connect I210 directly to Micrel KSZ8721 without magnetics.
The sample with old controller
http://www.intel.ru/content/dam/doc/application-note/8255x-fast-ethernet-controllers-without-magnetics-appl-note.pdf
I'am using 100Mbit mode - set in ethernet drivers.
Connect as datasheet:
Connect two chips like this (Left WGI210AT -- Righ Micrel KSZ8721BL):
board is working, two chips connecting each other, send and receive packets.
But, I'v got a lot of strange error on ethernet KSZ8721(Right side schema) when traffic increase (500-1000packets/sec)
May be, need to disable Auto-MDIX ?
Thanks
