DS90UB933-Q1: drive strength

Sherry Liang

Dear team,

Could you please help clarify below drive strength register? It means larger output amplitude? Or larger output current? When do I need to set this bit to 1?

Thanks & Best Regards,

Sherry

Hello Sherry,

SER reg0x01[6] RDS bit only configures the drive strength of GPO pins (pins 15-18) when set as outputs. This bit has nothing to do with the forward channel signal strength!

Hello Sherry,

Any reason why you are looking for these details?

I do not have specific numbers now, but if this is very important for you, I can discuss this internally with the team!
