ULPI Hi-Speed Universal Serial Bus On-The-Go transceiver
Rev. 01 — 30 May 2007
Product data sheet
1. General description
The ISP1506 is a Universal Serial Bus (USB) On-The-Go (OTG) transceiver that is fully
compliant with Ref. 1 “Universal Serial Bus Specification Rev. 2.0”, Ref. 2 “On-The-Go
Supplement to the USB 2.0 Specification Rev. 1.2” and Ref. 3 “UTMI+ Low Pin Interface
(ULPI) Specification Rev. 1.1”.
The ISP1506 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 USB host, peripheral and OTG devices.
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) and any system chip set to interface with the physical layer of the
USB through an 8-pin interface.
The ISP1506 can interface to devices with digital I/O voltages in the range of 1.65 V to
1.95 V.
The ISP1506 is available in HVQFN24 package.
