TUSB217A
- Wide supply voltage range: 2.3 – 6.5 V
- Ultra-low USB disconnect and shutdown power consumption
- Provides USB 2.0 high-speed signal conditioning
- Compatible with USB 2.0, OTG 2.0 and BC 1.2
- Support for low-speed, full-speed, high-speed signaling
- Integrated BC 1.2 Charging Downstream Port (CDP) and Dedicated Charging Port (DCP) controllers that dynamically changes per DCP/CDP pin
- Host or device agnostic
- Supports up to 5-m cable length
- Four selectable signal boost (edge boost along with DC boost) settings through the external pull-down resistor values
- Three selectable RX equalization settings through the pull-up-or-down to compensate ISI jitter for high-loss applications
- Supports up to 10-m cable length with two TUSB217A devices
- Scalable solution – devices can be daisy chained for high loss applications
- RWB is pin compatible with TUSB211/212/214/216
The TUSB217A is a third-generation USB 2.0 high-speed signal conditioner 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. In addition, the TUSB217A includes a pre-equalization function to improve the receiver sensitivity and compensate the inter-symbol interference (ISI) jitter in application with longer cable length. USB low-speed and full-speed signal characteristics are unaffected by the TUSB217A.
The TUSB217A improves signal quality without altering packet timing or adding propagation delay or latency.
The TUSB217A helps a system to pass the USB 2.0 high-speed near end eye compliance with a cable as long as 5 meters.
The TUSB217A is compatible with the USB On-The-Go (OTG) and battery charging (BC 1.2) protocols. The Integrated BC 1.2 battery charging controller can be enabled through a control pin.
