Abstract:

The ISP1504A1; ISP1504C1 (ISP1504x1) is a Universal Serial Bus (USB) On-The-Go (OTG) transceiver that is fully compliant with Universal Serial Bus Speci?cation Rev. 2.0, On-The-Go Supplement to the USB 2.0 Speci?cation Rev. 1.2 and UTMI+ Low Pin Interface (ULPI) Speci?cation Rev. 1.1. The ISP1504x1 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 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-Speci?c Integrated Circuits (ASICs), Programmable Logic Devices (PLDs) and any system chip set to interface with the physical layer of the USB through a 12-pin interface. The ISP1504x1 can interface to devices with digital I/O voltages in the range of 1.65 V to 3.6 V. The ISP1504x1 i
