15.11 Ethernet RJ45 connector (CN8)
The STM32H573I-DK board supports 10 Mbit/s / 100 Mbit/s Ethernet communication with its PHY and the CN8
integrated Ethernet RJ45 connector. The Ethernet PHY is connected to the MCU via the RMII interface.
The 25 MHz clock for the PHY is sourced from the on-board 25 MHz oscillator X3.
The 50 MHz clock for the MCU (derived from the 25 MHz crystal oscillator) is provided by the RMII_REF_CLK of
the PHY.
The yellow LED and the green LED are located inside the Ethernet RJ45 connector.
