1.General descriptionThe ISP1705 is a UTMI+ Low Pin Interface (ULPI) Hi-Speed Universal Serial Bus (USB)transceiver that is fully compliant with Universal Serial Bus Specification Rev.2.0,On-The-Go Supplement to the USB2.0 Specification Rev.1.3 and UTMI+ Low PinInterface (ULPI) Specification Rev.1.1.The ISP1705 can transmit and receive USB data at high speed (480 Mbit/s), full speed(12 Mbit/s) and low speed (1.5 Mbit/s), and provides a pin-optimized, physical layerfront-end attachment to the USB host, peripheral or OTG controller with Single Data Rate(SDR) or Dual Data Rate (DDR) ULPI link. The ISP1705 can transparently transmit andreceive UART signaling.It is ideal for use in portable electronic devices, such as mobile phones, digital stillcameras, digital video cameras, Personal Digital Assistants (PDAs) and digital audioplayers. It allows USB Application-Specific Integrated Circuits (ASICs), ProgrammableLogic Devices (PLDs) or any system chip set to interface with the physical layer of theUSB through an 8-pin (DDR) or 12-pin (SDR) interface.The ISP1705 can interface to devices with digital I/O voltages in the range of 3.0 V to3.6 V.The ISP1705 is available in HVQFN36 and TFBGA36 packages.2.FeaturesI Fully complies with:N USB: Universal Serial Bus Specification Rev.2.0N OTG: On-The-Go Supplement to the USB 2.0 Specification Rev.1.3N ULPI: UTMI+ Low Pin Interface (ULPI) Specification Rev.1.1I Interfaces to USB host, peripheral or OTG cores; optimized for portable devices orsystem ASICs with built-in ULPI linkI Complete Hi-Speed USB physical front-end solution that supports high speed(480 Mbit/s), full speed (12 Mbit/s) and low speed (1.5 Mbit/s)N Integrated 45 Ω ±10 % high-speed termination resistors, 1.5 kΩ ±5 % f...
