USB334x

Note 4-5

The resistor value follows the 27% Resistor ECN published by the USB-IF.

Note 4-6

The values shown are valid when the USB RegOutput bits in the USB IO & Power Management

Note 4-7

An automatic waiver up to 200mV is granted to accommodate system-level elements such as

measurement/test fixtures, captive cables, EMI components, and ESD suppression. This parameter

can be tuned using VariSense technology, as defined in Section 7.1.3.1, "HS Compensation
