Berisha, who joined Burnley from Hamburg last summer in a £300,000 deal, will work on getting back to match fitness during his time with former Champions League qualifiers Rosenborg.
Speaking about the move for the 23-year-old, Owen Coyle told the club's website: "He has been out for a year and is not quite ready to start in our team just now.
"This'll enable him to get match games which are vital to his rehabilitation."
Coyle added: "If he goes there he will hopefully come back on the January 1 as a new player and ready to play a part for Burnley Football Club. He desperately needs games."
