fsk demodulator with xr2211

You need to be a little more specific about what kind of help you need. You can go to **broken link removed** and download the datasheet on the 2211. All of the formulas required to calculate mark/space frequencies as well as pin functions are explained in the datasheet. Look there first and if that doesn't answer your questions, then post again with more detail.

Hope that helps.
