USB3450 Hi-Speed USB Host or Device PHY With UTMI+ Interface Highlights
● USB-IF “Hi-Speed” certified to the Universal Serial Bus Specification Rev. 2.0
● Interface compliant with the UTMI+ Specification, Rev. 1.0
● Functional as a host or device PHY
● Supports HS, FS, and LS data rates
● Supports FS pre-amble for FS hubs with a LS device attached (UTMI+ Level 3)
● Supports HS SOF and LS keep alive pulse
● Low Latency Hi-Speed Receiver (43 Hi-Speed clocks Max)
● Internal 1.8 volt regulators allow operation from a single 3.3 volt supply
● Internal short circuit protection of DP and DM lines to VBUS or ground
● Integrated 24MHz Crystal Oscillator supports either crystal operation or 24MHz external clock input
● Internal PLL for 480MHz Hi-Speed USB operation
● Supports Hi-Speed USB and legacy USB 1.1 devices
● 55mA Unconfigured Current (typical) - ideal for bus powered applications
● 83uA suspend current (typical) - ideal for battery powered applications
