General Description

The USB3318 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

■ 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 to 3.3V 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 2.0 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

■ 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)
