can i use a xbee coordinator

Yes, you can.

But the real question is: where you want to ?

Rajeshreddy, Yes, you can use an XBee ZB module as a ZigBee Coordinator with other Digi XBee ZB modules or with 3rd party ZIgBee routers and End points providing they are using the Zigbee pro public profile. This can be done by setting the ZS parameter to either a 2 or 3 as needed.
