1. General description
2. Features
The ISP1508 is a UTMI+ Low Pin Interface (ULPI) Universal Serial Bus (USB) transceiver
that is fully compliant with Universal Serial Bus Specification Rev. 2.0 , On-The-Go
Supplement to the USB 2.0 Specification Rev. 1.2 and UTMI+ Low Pin Interface (ULPI)
Specification Rev. 1.1 .
The ISP1508 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 layer
front-end attachment to the USB host, peripheral or OTG Controller with Single Data Rate
(SDR) or Dual Data Rate (DDR) ULPI interface. The ISP1508 can transparently transmit
and receive UART signaling.
It is ideal for use in portable electronic devices, such as mobile phones, digital still
cameras, digital video cameras, Personal Digital Assistants (PDAs) and digital audio
players. It allows USB Application-Specific Integrated Circuits (ASICs), Programmable
Logic Devices (PLDs) or any system chip set to interface with the physical layer of the
USB through an 8-pin (DDR) or 12-pin (SDR) synchronous digital interface.
The ISP1508 can interface to devices with digital I/O voltages in the range of 1.4 V to
1.95 V.
The ISP1508 is available in TFBGA36 package.
