ISP1514A
General Description
The ISP1514A 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 and UTMI+ Low Pin Interface (ULPI) Specification Rev. 1.1.
The ISP1514A 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 controller with Single Data Rate (SDR) ULPI link. The ISP1514A 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 a 12-pin SDR interface.
The ISP1514A can interface to devices with digital I/O voltages in the range of 1.65 V to 1.95 V.
The ISP1514A is available in WLCSP25 package.
