OTi-2208 NF USB Data Bridge Controller


The OTi-2208NF is a single chip, cost-effective, and high-performance USB2.0 Mass Storage Class Peripheral controller targeted for applications of data transfer between PCs. The design complies with USB High Speed Specification (480Mb/s), Version 2.0.

The OTi-2208NF has two USB interfaces for connecting two PCs. With stable clock slew-rate control, the controller can reduce the EMI issue.

The controller has one dedicated LED control pin and one optional LED control pin(GPIO). The LED display modes - operation, suspend, and standby, are programmable through the production program provided by Oti. Value-added application software for data transfer, synchronization, and data management is also available.

The Oti-2208NF is suitable for on-motherboard applications, especially for laptop computers. It could be designed as a standalone module in the motherboard and connected to one of the USB 2.0 high speed ports from the south bridge. The operating power of module could be supplied by another PC or laptop when the Oti-2208NF was connected to the USB port of another host through the USB cable. It will not consume any power of the local PC or laptop! Such system design may be good for some computing machines that work with the battery-power.
This controller can operate on Windows Vista, Win XP, and Win2000.

The OTi-2208NF is available in cost-saving 48-pin LQFP (7mm X 7mm) package. Another 64-pin or 100-pin package is also available for extending extra functions.
