RGMII Max Trace Length

[Balaji_ng]

Hi,

    I am designing I.MX6SoloX based PCB with dual AR8031 as in Sabre SDB.  The trace lengths of RGMII on my Layout are approximately 5.6 Inch because of the Placement Constraints. However, all the RGMII traces have an unsplit Ground Reference Plane. As per RGMII standards, I understand maximum RGMII trace length is 6 Inches.

In the above context, let me know if the 5.6 Inch is fine.

Regards,

Balaji.V

Hi Balaji

i.MX does not impose additional restrictions on length, so

5.6 Inch would be fine.

Best regards
