I currently have a design that utilizes a XR-2209 fro company called Exar. It is an 8 pin VCO that has dual output (square wave and triangular wave, square wave is what is used). This part is obsolete and looking for an alternate. Any suggestions?

Thank you Bob. Unfortunately the suggested part was not in the freq range needed (I neglected to put that in my original post, my bad). I have implemented a very simple 555 timer configured as a VCO which works well for my application. Thank you again for your response.
