6.9 Typical Characteristics – Eye Diagrams

Figure 6-3 and Figure 6-4 show a side by side comparison of 480 Mbps USB 2.0 HS signals through calibration traces (without the device) and a typical TMUXHS221 channel. Attenuation of the vertical and horizonal eye opening through the device is minimal. The mux device also adds a very negligble amount of jitter to the signals.
