AM6442: LVCMOS Drive Strength

Hello Thierry HAUSER

Thank you for the query.

Is there any way to modify drive strength of IO configured in LVCMOS ?

It seems that it isn't possible : 

It could be very usefull to manage RGMII interfaces.

Drive strength configuration is currently not supported. The default drive strength is it is the only configuration used for SoC-level timing closure.

What is the equivalent output impedance?

Let me check internally and update you.

Hello Thierry HAUSER

Please refer input i received from the simulation expert

Yes I believe 60 ohm is the correct equivalent impedance corresponding to the nom drive strength setting for LVCMOS
