Manikandan · ‎2025-02-06

Hi Team,

We are using the STM32H753VIH6 in our design.

We are having MAC to MAC connection with Realtek GMAC port and STM MAC port.

The schematics connections is in the attachment.

Now we would like to generate 50MHz reference clock from STM32 to Realtek.

We are unable to generate the reference clock. Kindly help us to resolve the issue.

Thanks
