OT7300 single IC chip Super Speed USB 3.0 Host to Host bridging controller

The OT7300 is a single-chip SuperSpeed USB 3.0 Host-to-Host bridge controller specially designed for connecting two USB Host systems either between Desktop/Laptop PC, Tablet, Smart or Smart TV.

The OT7300 uses 'Hybrid Multi-Class' channel that allows two USB host systems to share their keyboard, mouse, network, mass storage, display, and multimedia capabilities. The OT7300 links two USB hosts to exchange data through mass storage class driver or RNDIS (Remote Network Driver Interface Spec) Both USB sides support USB mass storage mode that allows the host system automatically launching the custom application which stored in external flash memory.

The OT7300 also provides flexible endpoint assignment mechanism to easily support multi-USB class protocol. Custom applications can be easily implemented through this high performance controller.
