USB332x
Miniature Hi-Speed USB
Transceiver with 1.8V
ULPI Interface
PRODUCT FEATURES
Integrated ESD protection circuits
— 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
— No degradation of Hi-Speed electrical
characteristics
— Allows single USB port of connection by
providing switching function for:
– Battery charging
– Stereo and mono/mic audio
– USB Full-Speed/Low-Speed data

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
— 1.8V IO Voltage (±10%)
Integrated battery to 3.3V LDO regulator
— 2.2uF bypass capacitor
— 100mV dropout voltage
“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
External Reference Clock operation
— 0 to 3.6V input drive tolerant
— Able to accept “noisy” clock sources as reference
to internal, low-jitter PLL
— Frequencies: 12, 13, 19.2, 24, 26, 27, 38.4, 52 or
60MHz
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 1.3 specification
Supports the OTG Host Negotiation Protocol (HNP)
and Session Request Protocol (SRP)
UART mode for non-USB serial data transfers
