USB334x

Enhanced Single Supply Hi-Speed USB ULPI

Transceiver

• External Reference Clock operation available

- ULPI Clock Input Mode (60 MHz 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 (USB3343)

• 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 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

Product Features

• USB-IF Battery Charging 1.2 Specification Com-

pliant

• Link Power Management (LPM) Specification

Compliant

• Integrated ESD protection circuits

- Up to ±25kV 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 (USB3341, USB3346, and

USB3347)

- Allows single USB port of connection by pro-

viding switching function for:

–Battery charging

–Stereo and mono/mic audio

–USB Full-Speed/Low-Speed data

• RapidCharge Anywhere™ Provides:

• Industrial Operating Temperature -40C to +85C

• 24 pin, QFN RoHS Compliant package

(4 x 4 x 0.90 mm height)

- 3-times the charging current through a USB

port over traditional solutions

- USB-IF Battery Charging 1.2 compliance to

any portable device

Applications

- Charging current up to 1.5Amps via compati-

ble USB host or dedicated charger

- Dedicated Charging Port (DCP), Charging

(CDP) & Standard (SDP) Downstream Port

support

The USB334x 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.
