Hello,
we have connect the PHY-MAC with the AM65xx-MAC directly without discrete serial resistors.
It is our first prototype and we dont have any knowledgebase in MAC-using.
But i have got a schematic-review from Texas-Instruments and they wrote:
"RGMII signal integrity requires series resistors close to the TX end of all 12 nets."
The old Version was planed with RGMII-Interface, but the new will work with MII.
My question, because i dont found any additional informations about discrete-MAC-serial-resistors,
can give me anybody more information about that?
The problem is, if we require these resistors, the routing of the MAC-interface-signals is more
difficult.
best regards
Christian Braune
