Hi,

Thanks for your update. As I understand it, you have some inquiries related to the E-Tile Native PHY in the S10DX devices as compared to GX devices. For your information, in the S10DX devices, it consists of P-tile and E-tile only. For the E-tile Native PHY, it only supports PCS-direct or PMA only mode. There is no standard PCS like L/H-tile available. In other words, you would not be able to direct migrate from L/H-Tile Native PHY to E-Tile Native PHY. As for the P-tile, it is used for PCIe or UPI application only. For the PCIe application, you would need to use the Hard IP to leverage the P-tile XVCR.

Please let me know if there is any concern. Thank you.

Best regards,
