General Description
The USB3319 is a highly integrated Hi-Speed USB 2.0 Transceiver (PHY) that supports systems architectures based on a 13MHz reference clock. It is designed to be used in both commercial and industrial temperature applications.

PRODUCT FEATURES Data Brief
■ USB-IF “Hi-Speed” compliant to the Universal Serial Bus Specification Rev 2.0
■ Interface compliant with the ULPI Specification revision 1.1 as a Single Data Rate (SDR) PHY
■ 1.8V IO Voltage (±10%)
■ flexPWR® 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
■ Supports FS pre-amble for FS hubs with a LS device attached (UTMI+ Level 3)
■ Supports HS SOF and LS keep-alive pulse
■ Includes full support for the optional On-The-Go (OTG) protocol detailed in the On-The-Go Supplement Revision 1.0a specification
■ Supports the OTG Host Negotiation Protocol (HNP) and Session Request Protocol (SRP)
■ Allows host to turn VBUS off to conserve battery power in OTG applications
■ Support OTG monitoring of VBUS levels with internal comparators
■ “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
■ Internal 5V cable short-circuit protection of ID, DP and DM lines to VBUS or ground
■ 13MHz Reference Clock Operation
    — 0 to 3.6V input drive tolerant
    — Able to accept “noisy” clock sources
■ Internal low jitter PLL for 480MHz Hi-Speed USB operation
■ Internal detection of the value of resistance to ground on the ID pin
■ Integrated battery to 3.3V LDO regulator
    — 2.2uF bypass capacitor
    — 100mV dropout voltage
■ Integrated ESD protection circuits
    — Up to ±15kV without any external devices
■ Carkit UART mode for non-USB serial data transfers
■ Integrated USB Switch
    — Allows single USB port of connection
    — High speed data
    — Battery charging
    — Stereo and mono/mic audio
    — USB1.1 data
■ Industrial Operating Temperature -40°C to +85°C
■ Packaging Options
    — 24 pin QFN lead-free RoHS compliant package (4 x 4 x 0.90 mm height)
    — 25 ball VFBGA lead-free RoHS compliant package also available; (3 x 3 x 0.88mm height)
