Hi-Speed USB Transceiver with 1.8V ULPI Interface - 13MHz Reference Clock
Application Diagrams
Steady state voltage at the VBUS pin must not be
allowed to exceed VVMAX.
RVBUS may be installed in this configuration to
assist in protecting the VBUS pin. 820 Ohms
will protect against VBUS transients up to
8.5V. 10K Ohms will protect against
transients up to 10V.
