RF, XBee Module with AT8951

Hi,

I am new with RF interfacing and I am using it in a project.
Nothing is complicated, just recieve a bunch of Analoge data from several sensors use the internal ADC of the 8951 and sent a packed binary data to the XBee module, and sent it to another Xbee module using the XB24 wire antenna.

I am currently looking for a basic schimatic circuit that shows the connection of the the XBee with the 8951. Do you guys have any links or source of information about how to interface the 8951 with the XBee module's PINs?

Any help would really be appriciated .
