TUSB217A-Q1 USB 2.0 High-Speed Signal Conditioner

Texas Instruments' TUSB217A-Q1 is a 3rd-generation USB 2.0 high-speed signal conditioner designed to compensate AC loss (due to capacitive load) and DC loss (due to resistive loss) in the transmission channel. The device 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 device includes a pre-equalization function to improve the receiver sensitivity and compensate the inter-symbol interference (ISI) jitter in applications with longer cable lengths.

USB low-speed and full-speed signal characteristics are unaffected by the TUSB217A-Q1. The signal conditioner improves signal quality without altering packet timing or adding propagation delay or latency. The TUSB217A-Q1 helps a system pass the USB 2.0 high-speed near-end eye compliance with a cable length up to 5 meters. The device is compatible with USB on-the-go (OTG) and battery charging (BC 1.2) protocols. The integrated BC 1.2 battery charging controller is enabled through a control pin.
