Combined with 1000Base-T1PHY chip, SJA1105REL/SEL can realize 1000Base-T1 communication function?
Hello DYW,
I hope all is great with you. Thank you for using the NXP communities.
In this case, each port can be independently configured for 10/100 Mbit/s MII/RMII or 10/100/1000 Mbit/s RGMII operation. The SGMII port on the SJA1105R/S can be configured for 10/100/1000 Mbit/s operation.
Please let me know if I misunderstood your question.
I hope this information helps.
Regards,
David
