USB331x Highly Integrated, Hi-Speed USB 2.0 ULPI Transceiver (PHY) Family for Portable Consumer Electronics Applications
The USB331x family of Hi-Speed USB 2.0 transceivers provides a highly integrated, small footprint solution well-suited for portable consumer electronics devices including cell phones, PDAs, portable media players and GPS/personal navigation devices. This family of devices eliminates the need for external USB switches and 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.
