ISO7340C: is there a fixed working frequency inside the digital Isolator?

Part Number: ISO7340C

Hi, 

I am thinking to use TI digital isolator in my design. but I have some questions need to be clarified:

1. I know TI uses capacitor isolation architecture. is the frequency crossing the isolation capacitor fixed or variable? my application is sensitive to some frequencies. I would like to know if the noise could be problem.

2. some isolators, like RS485 transceiver, with power. Does the power supply use inductor inside? does it work in strong magnetic field?

Thanks,

Jeff
