Hi Beau

There are Don Lancaster's "magic sine" algorithms, a special form of PWM that minimizes harmonics.

 PIC code is there, but it is a sure bet the SX could do it more efficiently.  What frequency range are you looking at?   

There are also the MF10 series digital filter chips, that can generate sine waves (with feedback from output to input) dependent on the input clock frequency.  Audio range and below.  There are also the DDS chips, like the AD9850, that cover a huge frequency range from sub Hertz to 60 mhz.
