1 TUSB217AEVM-BC

The TUSB217A 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 TUSB217A speeds up the transition edges of a USB 2.0 high-speed signal with an edge booster and increases static levels with a DC boost function. The TUSB217A includes a pre-equalization function to improve the receiver sensitivity and compensate the inter-symbol interference (ISI) jitter. USB 2.0 low-speed and full-speed signal characteristics are unaffected by the TUSB217A.

The integrated Charging Downstream Port (CDP) mode and Dedicated Charging Port (DCP) mode BC 1.2 battery charging controller can be controlled via the DCP/CDP pin.

The TUSB217AEVM-BC was designed to be used as a path connection between a USB 2.0 host and a USB 2.0 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.
