USB3317
Hi-Speed USB Transceiver
with 1.8V-3.3V ULPI Interface -
26MHz Reference Clock
PRODUCT FEATURES
Data Brief
USB-IF “Hi-Speed” compliant to the Universal Serial
Bus Specification Rev 2.0
Interface compliant with the ULPI Specification
revision 1.1 as a Single Data Rate (SDR) PHY
1.8V to 3.3V IO Voltage (+/- 10%)
SMSC flexPWRTM 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
Integrated battery to 3.3V LDO regulator
— 2.2uF bypass capacitor
— 100mV dropout voltage
Integrated ESD protection circuits
— Up to +-15kV without any external devices
Carkit UART mode for non-USB serial data transfers
Industrial Operating Temperature -40°C to +85°C
Packaging Options
— 24 pin QFN lead-free RoHS compliant package
(4 x 4 x 0.90 mm height)
— 25 ball VFBGA lead-free RoHS compliant package also
available; (3 x 3 x 0.88mm height)
Applications
The USB3317 is targeted for any application where a Hi-
Speed USB connection is desired and when board
space, power, and interface pins must be minimized.
The USB3317 is well suited for:
Cell Phones
PDAs
MP3 Players
GPS Personal Navigation
Scanners
External Hard Drives
Digital Still and Video Cameras
Portable Media Players
Entertainment Devices
Printers
Set Top Boxes

N/A ID pin of the USB cable. For non-OTG
applications this pin can be floated. For
an A-Device ID is grounded. For a B-
Device ID is floated.
N/A VBUS pin of the USB cable. This pin is
used for the Vbus comparator inputs and
for Vbus pulsing during session request
protocol.
N/A Regulator input. The regulator supply can
be from 5.5V to 3.1V.

N/A 3.3V Regulator Output. A 2.2uF (<1 ohm
ESR) bypass capacitor to ground is
required for regulator stability. The
bypass capacitor should be placed as
close as possible to the USB3317.
N/A D- pin of the USB cable.
