S32K358 RGMII Interface

VNeve — Mon, 23 Dec 2024 14:03:09 GMT

I am looking to interface 1Gbps Ethernet PHY to S32K358 through RGMII.

On searching for pins to map for the interface I found that in IO signal table only 2 Tx and 2 Rx pin options are available while 4 Tx and 4 Rx pins are required to complete the interfacing. Other available Tx and Rx pins shows for "(MII Mode Only)" and possibly can't be use as RGMII interface. Is there any application note or reference schematic available?

I have read the communication on forum but not found any conclusive answers.

Please help here. Thanks!!

GMAC of S32K358 support the RGMII for 1000 Mbits/sec.

Please refer the Schematic in design file in this link. You can use the same pins for RGMII :--

Also refer the excel sheet in the attachment of the reference Manual, for GMAC pin details.
