SGMII MAC side interface polarity mistake at 88E1512 with TI6638k2k processor(MAC)

suma Reddy

Hi,

We are using 88E1512 PHY with TI 6638k2k processor.

In the schematic at PHY side, SGMII Receive signal P & N signals polarity reversed. Due to this the LINK is not up and SGMII auto negotiation is not happening.

Kindly suggest.
