Information

The USB3315 is a highly integrated Hi-Speed USB 2.0 Transceiver (PHY) that supports systems architectures based on a 24MHz reference clock. It is designed to be used in both commercial and industrial temperature applications. The USB3315 meets all of the electrical requirements to be used as a Hi-Speed USB Host, Device, or an On-the-Go (OTG) device. In addition to the supporting USB signaling the USB3315 also provides USB UART mode USB3315 uses the industry standard UTMI+ Low Pin Interface (ULPI) to connect the USB PHY to the Link. The industry standard ULPI interface uses a method of in-band signaling and status byte transfers between the Link and PHY, to facilitate a USB session. By using in-band signaling and status byte transfers the ULPI interface requires only 12 pins. The USB3315 uses SMSC’s “wrapper-less” technology to implement the ULPI interface. This “wrapperless” technology allows the PHY to achieve a low latency transmit and receive time. SMSC’s low latency transceiver allows an existing UTMI Link to be reused by adding a UTMI to ULPI bridge. By adding a bridge to the ASIC the existing and proven UTMI Link IP can be reused.

Key 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
  • 24MHz 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
