USB3370

Note 4-7

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

Note 4-8

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

Note 4-9

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 of Section 7.0, "ULPI Register

Map".
