3 Description

The TUSB211A 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 TUSB211A 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 TUSB211A includes a pre-equalization function to 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 TUSB211A.

The TUSB211A improves signal quality without altering packet timing or adding propagation delay or latency.

The TUSB211A helps a system to pass the USB 2.0 high-speed near end eye compliance with a cable as long as 5 meters.

The TUSB211A is compatible with USB On-The-Go (OTG) and Battery Charging (BC) protocols.
