AM6442: RGMII max lenght

Thierry HAUSER

Part Number: AM6442

Hello,

What is the RGMII max length allowable for CPSW and PRU interfaces? Is there some specific limitations? or the rule of thumb of 6inches is applicable?

Thanks for your help.

Hello Thierry HAUSER

Thank you for the query.

There are no length constraints in particular but following the thumb rule of 4-6 inches is a good idea from the overall system performance including radiated emission.

Please refer below thread and also be sure to follow the datasheet timings. It is recommended to perform a timing analysis.
