SLLSEZ6C February 2019 – October 2020 TUSB216
The high-speed booster (combination of edge boost and DC boost) improves the eye width for USB2.0 high-speed signals. It is direction independent and by that is compatible to OTG systems. The BOOST pin is configuring the booster strength with different values of pull down resistors to set 4 levels of boosts, alternatively the boost level can be set via I2C register according to Section 7.4.6. Internal circuitry of the signal conditioner reduces possible overshoot.
