Texas Instruments TUSB217/TUSB217-Q1 USB 2.0 Signal Conditioners
Texas Instruments TUSB217/TUSB217-Q1 USB 2.0 High-Speed Signal Conditioners are designed to compensate for both AC loss (due to capacitive load) and DC loss (due to resistive loss) in the transmission channel. The TUSB217/TUSB217-Q1 has a patented design that speeds up transition edges of USB 2.0 high-speed signal with an edge booster. This booster also increases static levels with a DC boost function. The TUSB217/TUSB217-Q1 includes a pre-equalization function to improve the receiver sensitivity and compensate for the ISI jitter in an application with a longer cable length. USB low-speed and full-speed signal characteristics are unaffected by the TUSB217/TUSB217-Q1.The Texas Instruments TUSB217/TUSB217-Q1 USB 2.0 High-Speed Signal Conditioners improve signal quality without altering packet timing or propagation delay, making it ideal for applications requiring low latency. This conditioner helps a system to pass the USB 2.0 high-speed electrical near-end eye compliance tests with a cable as long as 5 meters. The TUSB217/TUSB217-Q1 is compatible with the USB On-The-Go (OTG) and Battery Charging (BC 1.2) protocols.
