| USB331x Family Highly Integrated, Hi-Speed USB 2.0 ULPI Transceiver Family for Portable Consumer Electronics Applications The USB331x family of Hi-Speed USB 2.0 transceivers provides a highly integrated, small footprint solution designed for portable consumer electronics devices including cell phones, PDAs, portable media players and GPS/personal navigation devices. The USB331x family eliminates the need for external USB switches and electrostatic discharge (ESD) protection devices, which minimizes eBOM part count and printed circuit board (PCB) area. The USB331x provides an extremely flexible solution which allows the USB connector to act as a single port of connection for high speed data transfer, battery charging and stereo/mono audio accessories. Highlights n Highly integrated, Hi-Speed USB 2.0 n SMSC flexPWRTM technology transceivers Integrated USB switch Internal ESD protection circuits Integrated 3.3V LDO regulator External passive components minimized n Industry's best current ESD performance in a Hi-Speed USB transceiver 8kV HBM 8kV/15kV IEC (contact/air) No external ESD protection circuits required n Ability to use the USB connector as a single port of connection Switch Hi-Speed data, battery charging and stereo/mono audio accessories n n n n n Variable I/O voltage capability (fixed 1.8V or a range of 1.8V to 3.3V) Low power and standby modes of operation to minimize power consumption Flexible reference clock to support major system clock frequencies - 13MHz, 19.2MHz, 24MHz and 26MHz Robust design tolerates "noisy" clock and power supplies Small package size and very low eBOM part count Hi-Speed USB On-The-Go (OTG) - host and device capable Supports commercial (0 to 70C) and industrial (-40 to 85C) temperature ranges Target Applications n n n n n n Cell Phones Smart Phones PDAs GPS Personal Navigation Devices Personal Media Players (PMPs) Digital Still and Video Cameras n n n n n n External Hard Disk Drives Printers Set-top Boxes Digital TVs Gaming Consoles Industrial Systems Features and Benefits FEATURES BENEFITS Integrated USB switch and ESD protection Provides lower eBOM part count and smaller PCB footprint area USB utilized as a single port of connection Reduction of end product size and cost SMSC flexPWR technology Flexible and easy-to-use solution Ability to tolerate "noisy" clocks and power supplies Small package footprint Longer battery life Faster time-to-market and lower product development cost Does not require costly filtering or clock generator circuits to preserve Hi-Speed eye diagram integrity Efficient PCB board space utilization Multiple clock input frequencies supported Eliminates cost and size of external crystal oscillator for typical systems What is SMSC flexPWR Technology?
