MICROCHIP USB3500-ABZJ

The USB3500 is a stand-alone Hi-Speed USB Physical Layer Transceiver (PHY). The USB3500 uses a UTM + interface to connect to an SOC or FPGA or custom ASIC. The USB3500 provides a flexible alternative to integrating the analog PHY block for new designs. The USB3500 provides a fully compliant USB 2.0 interface, and supports High-Speed (HS), Full-Speed (FS), and LowSpeed (LS) USB. The USB3500 supports all levels of the UTM + specification. The USB3500 can also, as an option, fully support the On-the-Go (OTG) protocol defined in the On-The-Go Supplement to the USB 2.0 Specification. On-the-Go allows the Link to dynamically configure the USB3500 as host or peripheral configured dynamically by software. For example, a cell phone may connect to a computer as a peripheral to exchange address information or connect to a printer as a host to print pictures. Finally the OTG enabled device can connect to another OTG enabled device to exchange information. All this is supported using a single low profile Mini-AB USB connector. Designs not needing OTG can ignore the OTG feature set. The USB3500 uses advanced proprietary technology to minimize power dissipation, resulting in maximized battery life in portable applications.
