Responding to: ???'s previous message
Are you sure you want a sinewave?
Some systems specify other waveforms.

Could you just filter a squarewave?

You could just feed an ADC with sine values from a lookup table, or use PWM.

You haven't given any details to decide which would be most suitable to your requirement.
