TUSB217A USB 2.0 High-Speed Signal Conditioners Texas Instruments TUSB217A USB 2.0 High-Speed Signal Conditioners are designed to compensate both AC loss (due to capacitive load) and DC loss (due to resistive loss) in the transmission channel. The TUSB217A leverages a patented design to speed up transition edges of 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 for the inter-symbol interference (ISI) jitter in applications with longer cable length. USB low-speed and full-speed signal characteristics are unchanged by the TUSB217A.
