Hi
No, this should not be necessary Saurabh, it seems like this module includes the external LF crystal. Please double check your connections and make sure they are as in the picture below. As for the external chip getting hot, that does not sound good. Some temperature increase should be expected when it's running, but if it is scorching hot I think there's some trouble with the HW. Please check that the soldering on the board is done correctly.
Best regards,
Simon
