I am planning to use a 25MHz crystal as HSE Xtal for STM32f107 and route the same 25MHz Clock as MCO out to drive the ethernet PHY Chip -LAN8742A.
From LAN8742A, 50MHz RMIIREFCLK is fed back to stm32f107 EMAC.
I want to know if there are any issues in doing so.
In Evaluation board, NUCLEO F207zG, they have connected seperate 25MHz crystal to the PHY Chip.
Looking for a quick response
Thanks and regards
