®
Technology
— Low current design ideal for battery powered
applications
— “Sleep” mode tri-states all ULPI pins and places the
part in a low current state
Supports FS pre-amble for FS hubs with a LS device
attached (UTMI+ Level 3)
Supports HS SOF and LS keep-alive pulse
Includes full support for the optional On-The-Go
(OTG) protocol detailed in the On-The-Go
Supplement Revision 1.0a specification
Supports the OTG Host Negotiation Protocol (HNP)
and Session Request Protocol (SRP)
Allows host to turn VBUS off to conserve battery
power in OTG applications
Support OTG monitoring of VBUS levels with internal
comparators
“Wrapper-less” design for optimal timing performance
and design ease
— Low Latency Hi-Speed Receiver (43 Hi-Speed clocks
Max) allows use of legacy UTMI Links with a ULPI
bridge
Internal 5V cable short-circuit protection of ID, DP
and DM lines to VBUS or ground
26MHz Reference Clock Operation
— 0 to 3.6V input drive tolerant
— Able to accept “noisy” clock sources
Internal low jitter PLL for 480MHz Hi-Speed USB
operation
Internal detection of the value of resistance to ground
on the ID pin
