AM6412: RGMII drive strength

Darshan Shah

Part Number: AM6412

Hi,

How to check the drive strength of the RGMII interface for AM6412? Drive strength seems to be on weaker side. Want to increase the drive strength.

Hello Darshan,

Thank you for the query.

Please provide some additional details.

As i understand, we do not have provision to set the drive strength.

I see rise time and fall time degraded and that is causing less than 1ns setup/hold time. What is the default drive strength?

Hello Darsha,

The drive strength is fixed, driven at the max strength and i do not have a number.

Please refer to the section below for the electrical timing

7.10.5.16.6.3 PRU_ICSSG RGMII Timing

Are you facing some issues while testing? Have you had a chance to do the timing analysis and i that something you could share.

We have the Giga bit ethernet working on the EVMs. Have you had a chance to review the EVM design files?
