The TUSB216I is a USB High-Speed signal conditioner designed to compensate both AC loss (due to capacitive load) and DC loss (due to resistive loss) in the transmission channel

The TUSB216I speeds up the transition edges of USB 2.0 high-speed signal with an edge booster and increases static levels with a DC boost function. The TUSB216I includes a pre-equalization function to improve the receiver sensitivity and compensate the inter-symbol interference (ISI) jitter. USB low-speed and full-speed signal characteristics are unaffected by the TUSB216I. The integrated CDP mode BC 1.2 battery charging controller can be enabled via a control pin.

The TUSB216IEVM was designed to be used in path connection between a USB host and a USB device. The EVM is designed to provide multiple connector options to help eliminate the use of adapters. The upstream interface to the EVM consists of three possible input connectors: a USB 2.0 Mini-B Receptacle, a USB 3.1 Type B Receptacle, and a USB 3.1 Type-A Plug. The downstream interface to the EVM consists of three USB 3.1 Type-A Receptacle output connectors. Each section of the EVM is detachable from the main board along the board perforations. The EVM can be connected to the system using various cable lengths to verify system operation under different conditions.

The TUSB216IEVM is designed to provide easy evaluation of the redriver device for various types of applications. The TUSB216IEVM is also meant to serve as a reference design to show a practical example of how to use the device in a mass-production system.
