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)
