Hello,
I'm a junior hardware engineer and I run into a small problem while designing a circuit using DP83867CS.
In my design only signal RX_D0 is being used while RX_D1 is left unconnected. In the datasheet of the chip it says (note, p. 39) that these 2 pins form an SGMII differential pair. And dummy straps are required on both of the pins. I think that it is required only when the signal (RX_D1) is used, and not required when the signal is not used. But I am not sure if i interpreted this correctly. Could someone tell me or provide me with a literature where I can find information about this ?
I will be thankful,
Kind Regards,
Marcin Kuchta
