Product Introduction

Overview

The TUSB217-Q1, produced by Texas Instruments, is a third-generation USB 2.0 high-speed signal conditioner designed to compensate for both AC and DC losses in the transmission channel. This device is particularly useful in applications where signal integrity is crucial over longer cable lengths or through high-loss transmission paths. The TUSB217-Q1 features a patented design that includes an edge booster and a DC boost function to improve the eye width of USB 2.0 high-speed signals, ensuring compliance with USB 2.0 high-speed electrical near-end eye tests even with cable lengths up to 5 meters.

The device is compatible with USB On-The-Go (OTG) and Battery Charging (BC) specifications and supports low speed, full speed, and high speed signaling. It is also host/device agnostic, making it versatile for various applications.

Q & A

  1. What is the primary function of the TUSB217-Q1?

    The primary function of the TUSB217-Q1 is to compensate for signal losses in USB 2.0 high-speed transmission channels, ensuring signal integrity over longer cable lengths or through high-loss transmission paths.

  2. What are the supported USB speeds by the TUSB217-Q1?

    The TUSB217-Q1 supports low speed, full speed, and high speed USB signaling.

  3. Is the TUSB217-Q1 compatible with USB On-The-Go (OTG) and Battery Charging (BC) specifications?
  4. What is the maximum cable length supported by the TUSB217-Q1?

    The TUSB217-Q1 supports cable lengths up to 5 meters.

  5. How does the TUSB217-Q1 adjust signal boost levels?

    The signal boost levels can be adjusted via external pull-down resistors connected to the BOOST pin.

  6. Can the TUSB217-Q1 be daisy-chained for longer distances?
  7. What is the temperature range of the TUSB217-Q1?

    The TUSB217-Q1 operates within a temperature range of -40°C to 105°C.

  8. Does the TUSB217-Q1 support I2C mode for configuration?
  9. How does the TUSB217-Q1 handle low speed and full speed signals?

    The TUSB217-Q1 automatically detects low speed and full speed connections and does not enable signal compensation for these speeds.

  10. What is the purpose of the CD and ENA_HS pins in the TUSB217-Q1?

    The CD pin indicates the connection status, and the ENA_HS pin indicates when high-speed boost is active. The states of these pins vary depending on the operating mode (low speed, full speed, high speed, or shutdown).
