Overview
The TUSB214IRWBR is a USB 2.0 High-Speed signal conditioner produced by Texas Instruments. It is designed to compensate for Inter-Symbol Interference (ISI) signal loss in transmission channels, ensuring optimal signal integrity. This device is particularly useful in applications where long cable lengths or high signal attenuation are present. The TUSB214IRWBR is compatible with USB 2.0, USB On-The-Go (OTG) 2.0, and Battery Charging (BC) 1.2 protocols, making it versatile for various USB-based systems.

Q & A
- What is the primary function of the TUSB214IRWBR?
The TUSB214IRWBR is a USB High-Speed signal conditioner designed to compensate for ISI signal loss in transmission channels.
- Which USB protocols is the TUSB214IRWBR compatible with?
The TUSB214IRWBR is compatible with USB 2.0, OTG 2.0, and BC 1.2 protocols.
- How is the AC boost configured on the TUSB214IRWBR?
The AC boost is configured through different values of an external pulldown resistor on the EQ pin, offering four selectable levels.
- What is the role of the DC_BOOST pin on the TUSB214IRWBR?
The DC_BOOST pin is used to set the DC gain of the device, with three different settings available via pin strap configuration.
- Does the TUSB214IRWBR support I2C configuration?
- What are the typical operating current levels for the TUSB214IRWBR in High-Speed mode?
The typical operating current levels are 22-30 mA for active mode, 14-22 mA for idle mode, and 0.55-1.5 mA for suspend mode.
- How does the TUSB214IRWBR handle Low Speed and Full Speed signals?
The TUSB214IRWBR automatically detects LS and FS connections and does not enable signal compensation for these speeds, leaving their signal characteristics unaffected.
- What is the maximum cable length supported by the TUSB214IRWBR?
The device supports up to 5 meters pre-channel or 2 meters post-channel cable length.
- Can the TUSB214IRWBR be used in shutdown mode?
- What are some common applications for the TUSB214IRWBR?
