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

• GPS Personal Navigation Devices

• Media Players/Viewers
