ISP1508B
General Description
The ISP1508B 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. 1.3 and UTMI+ Low Pin Interface (ULPI) Specification Rev. 1.1.
The ISP1508B 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 Double Data Rate (DDR) ULPI interface. The ISP1508B 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 ISP1508B can interface to devices with digital I/O voltages in the range of 1.4 V to 1.95 V. Its CHIP_SEL polarity is active LOW.
The ISP1508B is available in TFBGA36 package.
