Based on the context provided, there is no specific reference schematic available for the KSZ9131 PHY with the Apalis iMX8 8QM. However, it is recommended to refer to the module’s datasheet and the PHY’s datasheet for detailed connection and configuration guidelines. These documents typically include pin configurations, power supply requirements, and example circuit designs that can help avoid design errors. Additionally, utilizing existing reference designs for the KSZ9131 can significantly reduce the risk of design errors. If you need further assistance, consulting with experienced hardware designers or using design software for simulation and validation is advisable.

Using two Ethernet interfaces on Toradex Apalis iMX8 Quad Max module

Going through details and different datasheets/documents, it seems feasible to use two Ethernet interfaces. But, confusion arise when I checked Toradex pinout designer tool, there is one pin conflicts using two ethernet interfaces on Apalis iMX8 QuadMax module. I looked at the interface and try designing Ethernet PHY (using AR8031 or KSZ9131), the conflicting pins are optional output pins and could work without it. Also, when I checked Apalis datasheet (Section 5.3; Page 29), mentions using s…
