mance and design ease
- Low Latency Hi-Speed Receiver (43 Hi-
Speed clocks Max) allows use of legacy
UTMI Links with a ULPI bridge
• External Reference Clock operation available
- 19.2MHz Reference Clock needed
- ULPI Clock Input Mode (60MHz sourced by
Link)
- 0 to 3.6V input drive tolerant
- Able to accept “noisy” clock sources as refer-
ence to internal, low-jitter PLL
- Crystal support available
• 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 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 5x 0.90 mm height)
Applications
The USB3370 is the solution of choice for any applica-
tion where a Hi-Speed USB connection is desired and
when board space, power, and interface pins must be
minimized.

Description
ULPI Clock Out Mode:
60MHz ULPI clock output. All ULPI signals are driven
synchronous to the rising edge of this clock.
ULPI Clock In Mode:
Connect this pin to VDDIO to configure 60MHz ULPI
Clock IN mode as described in Section 5.5.1.
The PHY asserts NXT to throttle the data. When the
Link is sending data to the PHY, NXT indicates when
the current byte has been accepted by the PHY.
ULPI bi-directional data bus. DATA[0] is the LSB.
ULPI bi-directional data bus.
ULPI bi-directional data bus.
