Controlling Amplitude and Phase

Hi, I'm doing a redesign of a circuit.  The input  to my old circuit takes a 100kHz oscillator signal that feeds into opamps so I end up with a 2Vp-p 100kHz sinewave at the output.  

 

What I need  is to control the phase of the sinewave.  From my DSP I was thinking of using a DAC so I can control the Amplitude and Phase.  I only need one output.  Can someone give me some feedback on how to do this?

 

Thanks,

 

Brian
