Preheat the oven to 325°F.
In a food processor pulverize the Oreos, butter, sugar and salt. Pour into the pan and pat flat with your finger tips, bringing the Oreo crumbs up the sides slightly. Bake the crust for about 10 minutes or until set.
In a stand mixer, fitted with the Beater Blade, mix the cream cheese on low speed, scraping down the sides to make sure it is all smooth. Add the sugar and sour cream. Add the eggs one at a time, mixing well after each. Add the salt and vanilla. Split the batter into two bowls. Add the peanut butter to one bowl and add the jelly to the second. Place the pan on a baking sheet. Spread the peanut butter batter over the oreo crust, smoothing out the top. Very carefully add the jelly batter over the peanut butter batter.
Place the cheesecake in the center of the oven. Place a second baking sheet on a lower shelf and fill it with water. The water will create steam in the oven and prevent the cheese cake from developing a hard crust. Bake for about 60 minutes or until set in the center. The top will souffle slightly. Allow the cheesecake to cool to room temperature, then refrigerate until thoroughly chilled, at least 4 hours. After one hour in the refrigerate, loosely cover with plastic.
Carefully run a thin bladed knife around the edge of the pan. Pull out the pin. Unmold the cake from the pan.
