Vikas,
What is your application? Why do you need USB2.0 and not looking at our USB switches?
The better part will depend on your application needs. See some of the key differences below I highlighted using the TI.com parametric table compare feature.
USB 2.0 specification calls for signals up to 480Mbps. These switches have bandwidths >600MHz so they will be enough to cover that datarate.
For reliable signal integrity we recommend that you select a part that has a bandwidth that is 3 times the fundamental frequency.
The data rate is you need is
480Mbps
The fundamental frequency of a signal is half the data rate.
480/2 = 240 MHz
3 time the fundamental frequency
240MHz *3 = 720MHz
ps 600MHz should be able to handle USB2.0 but the above is our official recommendation.
Thank you,
Adam
