Applications
The USB3503 is targeted for applications where more
than one USB port is required. As mobile devices add
more features and the systems become more complex
it is necessary to have more than one USB port to take
communicate with the internal and peripheral devices.
 Mobile Phones
 Tablet Computers
 Ultra Mobile PCs
 Digital Still Cameras
 Digital Video Camcorders
 Gaming Consoles
 PDAs
 Portable Media Players
