Hi, I'm using TS3USB30 in a new design. The datasheet doesn't list the recommended value for the decoupling capacitor– what should the value of the decoupling capacitor be? Will 0.1 uF work?

you mean the decoupling cap for power supply? what is the data rate of your signal? normally use 1uf/0.1us to cover different frequency range.
Brian, thanks for responding. Yes, I mean decoupling capacitor for the power supply. I'm using the TS3USB30 to switch a USB 2.0 signal, so the data rate through the chip will be 480Mbps. Can you say more about the 1uf/0.1us heuristic you suggested? I am not sure how to apply that in this case.
The period of the signal will be 0.002083us, so would that mean I should use a 0.02uf capacitor? Looks like I can't get 0.02uf caps, but can get 0.022uf capacitors in 0402 or 0603 sizes.
