6.8 Typical Characteristics – S-Parameters

Figure 6-1 and Figure 6-2 show differential insertion loss and return loss repectively for a typical TMUXHS221 channel.

The excellent high speed performance at 240 MHz results in minimal attenuation to the USB 2.0 or eUSB2 HS signal eye

diagrams. Note: measurements are performed in TI evaluation board with board and equipment parasitics calibrated out.
