2.13.1

USB DC electrical characteristics

This table provides the DC electrical characteristics for the USB interface at USB_VDD_3P3 = 3.3 V.

2.13.2

USB AC electrical specifications

This table provides the USB clock input (USBn_CLKIN) AC timing specifications.

This figure provides the USB AC test load.

Notes:

1. The min VILand max VIH values are based on the respective min and max USB_VIN_3P3 values found in Table 3.

2. The symbol USB_VIN_3P3, in this case, represents the USB_VIN_3P3 symbol referenced in Section 2.1.2, “Recommended

operating conditions.”
