Customer question;

What are the bypass requirements for the 0.9V USB termination voltage (N27)? Does this pin cover both USB ports?

Hi Tom,

On the eval. board there is a 100nF bypass capacitor (C634) on VDD_USB_0P9 (ball N27), and 33uF+100nF in the LDO output (C23, C24). And yes, ball N27 covers both USB ports.

Best Regards

Biser
