SJA1105 with BroadR-Reach and 100Base-T PHY

Contributor III

I want to extend my i.MX6 Quad Board with multiple Ethernet ports.

I need in minimum one BroadR-Reach port and one standard 100Base-T Ethernet port. Therefor I thought to take the NXP SJA1105 with a TJA1100 PHY and a KSZ8081 PHY. The SJA1105  should connect over RGMII with the i.MX6Q.

Is it possible to connect Automotiv Ethernet PHY and Ethernet PHY to the SJA1105 in mixture mode? In that constallatoin I also have a mediaconverter between Automotive Ethernet and Ethernet.

Each SJA1105 port is individually configurable for any supported
type of the interface between MAC and PHY. The type of the transmission
media is not visible at the MAC/PHY interface PHY and only depends on the
capabilities of the PHY device(s) you connect to the switch.

Have a great day,
