TM4C1294NCPDT: Clocking Ethernet PHY trough system timer

Part Number: TM4C1294NCPDT


Hi Folks,

In one of my custom TM4C1294 based board, where an Ethernet link is added, there are very strict constraint (space and money) so I thought, is it possible to use PIOSC, generate the system clock, and trough a general purpose timer, generate a 25MHz clock on physical pin. Then, this pin should be routed to the OSC0 pin, that is as I know, can be driven from a single clock source and required to feed  the Ethernet PHY clocking system.

Is it possible?

Regards,

Norbert
