USB3300-EZK

Product Summary

The USB3300-EZK is a stand-alone Hi-Speed USB Physical Layer Transceiver (PHY). The USB3300 uses a low pin count interface (ULPI) to connect to a ULPI compliant Link layer. The ULPI interface reduces the UTMI+ interface from 54 pins to 12 pins using a method of in-band signaling and status byte transfers between the Link and PHY.This PHY was designed from the start with the ULPI interface. No UTMI to ULPI wrappers are used in this design which provides a seamless ULPI to Li nk interface.

Features

USB3300-EZK features: (1)USB-IF “Hi-Speed” certified to the Universal SerialBus Specification Rev 2.0; (2)Interface compliant with the ULPI Specification revision 1.1 in 8-bit mode.; (3)Industry standard UTMI+ Low Pin Interface (ULPI.) Converts 54 UTMI+ signals into a standard 12 pin Link controller interface.; (4)Supports FS pre-amble for FS hubs with a LS device attached (UTMI+ Level 3); (5)Supports HS SOF and LS keep-alive pulse.; (6)Includes full support for the optional On-The-Go(OTGprotocol detailed in the On-The-Go Supplement Revision 1.0a specification.; (7)Supports the OTG Host Negotiation Protocol (HNP) and Session Request Protocol (SRP.); (8)Allows host to turn VBUS off to conserve battery power in OTG applications.; (9)Supports OTG monitoring of VBUS levels with internalcomparators . Includes support for an external VBUS or fault monitor.; (10)Low Latency Hi-Speed Receiver (43 Hi-Speed clocks Max) allows use of legacy UTMI Links with a ULPI wrapper.; (11)Integrated Pull-up resistor on STP for interface protection allows a reliable Link/PHY start-up with slow Links (software configured for low power.); (12)Internal 1.8 volt regulator s allow operation from a single 3.3 volt supply.; (13)Internal short circuit protection of ID, DP and DM lines to VBUS or ground.; (14)Integrated 24MHz Crystal O scillator supports either crystal operation or 24MHz external clock input.; (15)Internal PLL for 480MHz Hi-Speed USB operation.; (16)54.7mA Unconfigured Current (typical) - ideal for bus powered applications.; (17)83uA suspend current (typical) - ideal for battery powered applications.
