I have a S32G Domain&Gateway project .

whether is the S32G can support two low speed interface for TJA1102.

1)i saw the reference circuit S32G+SJA1105Q+TJA1102, so it means the S32G can support low speed interface for TJA1102 by through the SJA1105.

2)the self of S32G can't support two low speed interface for TJA1102.

3)my understanding is correct or not .

Best regards.

TJA1102 is a single data rate, 100Base-T1 automotive PHY. S32G2 supports
100Mbps at all Ethernet ports. See S32G2RM, Sections 46.3 and 47.2.

Hi @bpe ,

Thanks for your help.

Yes, it looks that the S32G can support the all Ethernet ports.

the hardware design, we can using the different case for the project.

1) using S32G+SJA1105(SWITCH)+TJA1102 to design

2) using S32G(PFE_MAC) + TJA1102 to design

these are my understanding, would you like to share your comments. thanks.

Best regards.
