Part Number: AM5728

Customer wants to know if there a way to set USB PHY driver current/pre-emphasis through a register ?

They want to adjust the setting if available during USB Signal Integrity testing.

Hi Lawrence,

The current and pre-emphasis is not user adjustable. Please refer to the layout guidelines for this device (SPRAAR7) when creating the PCB design and the default values should be more than sufficient.
