USB3320
Highly Integrated Full Featured
Hi-Speed USB 2.0 ULPI
Transceiver
PRODUCT FEATURES
Datasheet
 Integrated ESD protection circuits
â Up to ±15kV IEC Air Discharge without external
devices
 Over-Voltage Protection circuit (OVP) protects the
VBUS pin from continuous DC voltages up to 30V
 Integrated USB Switch
â No degradation of Hi-Speed electrical
characteristics
â Allows single USB port of connection by
providing switching function for:
â Battery charging
â Stereo and mono/mic audio
â USB Full-Speed/Low-Speed data
 flexPWR® Technology
â Low current design ideal for battery powered
applications
â âSleepâ mode tri-states all ULPI pins and places
the part in a low current state
â 1.8V to 3.3V IO Voltage (±10%)
 Integrated battery to 3.3V regulator
â 2.2uF bypass capacitor
â 100mV dropout voltage
 âWrapper-lessâ design for optimal timing performance
and design ease
â Low Latency Hi-Speed Receiver (43 Hi-Speed
clocks Max) allows use of legacy UTMI Links with
a ULPI bridge
 Selectable Reference Clock Frequency
â Frequencies: 12, 13, 19.2, 24, 26, 27, 38.4, 52 or
60MHz - pin selectable
 External Reference Clock operation available
â ULPI Input Clock Mode (60MHz sourced by Link)
â 0 to 3.6V input drive tolerant
â Able to accept ânoisyâ clock sources as reference
to internal, low-jitter PLL
 Internal Oscillator operation available
â This mode requires external Quartz Crystal or
Ceramic Resonator
 Smart detection circuits allow identification of USB
charger, headset, or data cable insertion
 Includes full support for the optional On-The-Go
(OTG) protocol detailed in the On-The-Go
Supplement Revision 2.0 specification
 Supports Headset Audio Mode
 Supports the OTG Host Negotiation Protocol (HNP)
and Session Request Protocol (SRP)
 UART mode for non-USB serial data transfers
 Internal 5V cable short-circuit protection of ID, DP
and DM lines to VBUS or ground
 Industrial Operating Temperature -40°C to +85°C
 32 pin, QFN Lead-free RoHS Compliant Package
(5 x 5 x 0.90 mm height)
Applications
The USB3320 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 USB3320 is well suited for:
 Networking
 Audio Video
 Medical
 Industrial Computers
 Printers
 Repeaters
 Communication
SMSC USB3320
