TUSB217EVM User's Guide
1 TUSB217EVM
The TUSB217 is a USB High-Speed signal conditioner, designed to compensate for ISI signal loss in a
transmission channel.
The TUSB217 design is agnostic to USB Low and Full-Speed signals and does not affect FS and LS
signaling. High-Speed signals are compensated along with programmable DC gain to fine-tune device
performance to optimize the High-Speed signals at the connector.
This EVM was designed to be used as a medium connection between a USB host and a USB device. The
interface to the EVM consists of a USB 3.1 Type A Receptacle and a USB 3.1 Type B Receptacle.
Therefore, in order to connect the EVM to your system set up, the user most likely needs 2 USB 3.1 or
USB 2.0 Standard Type A
→ B cables. Your test setup should look similar to Figure 1 .
