Brady Green, 39, of Dublin, Ga., must also stay away from the former supermodel for the next two years under an order of protection.
Manhattan Criminal Court Judge James Burke warned Green that he would face up to 90 days in jail if he disobeys any of the court's orders.
Green and his lawyer left court without commenting.
Green was convicted in April of stalking Banks from coast to coast — calling her offices, showing up at her TV studios and sending her flowers. Police said he threatened to cut a staffer's throat for not telling him where Banks was.
When Green was arrested March 18, 2008, at a McDonald's restaurant near Banks' Manhattan studio, he told officers they "had a thing together," police said.
Banks, who did not attend Green's sentencing, testified during his trial that she feared for her safety, and for that of her staff and family.
The former Sports Illustrated cover girl said that because of Green, her company hired more security staff, her studio audiences are vetted more thoroughly, and security guards follow her everywhere.
Green testified that he was a Banks fan and had been enthusiastic about trying to get tickets for her show. He said his actions had been misunderstood.
But Assistant District Attorney Sean McMahon got Green to admit that he rode a bus for four days from Los Angeles to New York where he had no friends, relatives or job, and the first he thing he did was go to the building that houses Banks' studio.
Banks is executive producer and host of two popular TV shows, "America's Next Top Model" and "The Tyra Banks Show."
