AM3352: RGMII EMC issue

Simon Siepmann

Part Number: AM3352

Hello Sitara Team,

My customer reported EMC emission of 125MHz from RGMII TCLK.

Questions:

- Is the drive strength of the RGMII configurable?

- What measures will improve EMC noise?

Best Regards,

Simon

No, this is not possible.

Our Sitara EVM's have 22Ohm serial resistors on the RGMII lines.
