DRA829V: USB1_RCALIB and USB0_RCALIB resistor values

Arun M1

Part Number: DRA829V

Hello,

Can we use 500Ohm 5% for USB1_RCALIB and USB0_RCALIB resistor values, We are not using the same section (USB Interface USB0 and USB1) in our application.

Thanks

Arun,

We can't guarantee USB performance with a 5% resistor. I'm not sure I understand this part of your question:

"We are not using the same section (USB Interface USB0 and USB1) in our application." What do you mean by section? And what are you comparing your application to?

Best Regards,

Zack

Hello Zack,

The entire USB section is not connected and we are not using the interface. As I gone through the datasheet it is mentioned to keep a 500 ohms calibration resistance. Is it mandatory to pull down even if we are not using the USB peripheral.

Arun
