USB3320
Highly Integrated Full Featured Hi-Speed USB 2.0 ULPI
Transceiver
Features
⢠Integrated ESD protection circuits
- Up to ±15kV IEC Air Discharge without exter-
nal devices
⢠Over-Voltage Protection circuit (OVP) protects the
VBUS pin from continuous DC voltages up to 30V
⢠Integrated USB Switch
- No degradation of Hi-Speed electrical char-
acteristics
- Allows single USB port of connection by pro-
viding switching function for:
âBattery charging
âStereo and mono/mic audio
âUSB Full-Speed/Low-Speed data
⢠flexPWR® Technology
- Low current design ideal for battery powered
applications
- âSleepâ mode tri-states all ULPI pins and
places the part in a low current state
- 1.8V to 3.3V IO Voltage (±10%)
⢠Integrated battery to 3.3V regulator
- 2.2uF bypass capacitor
- 100mV dropout voltage
⢠âWrapper-lessâ design for optimal timing perfor-
mance and design ease
- Low Latency Hi-Speed Receiver (43 Hi-
Speed clocks Max) allows use of legacy
UTMI Links with a ULPI bridge
⢠Selectable Reference Clock Frequency
- Frequencies: 12, 13, 19.2, 24, 26, 27, 38.4,
52 or 60MHz - pin selectable
⢠External Reference Clock operation available
- ULPI Input Clock Mode (60MHz sourced by
Link)
- 0 to 3.6V input drive tolerant
- Able to accept ânoisyâ clock sources as refer-
ence to internal, low-jitter PLL
⢠Internal Oscillator operation available
⢠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 Sup-
plement 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 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
