Not necessarily.  Many oscillator circuits do not deliver a good sine 
wave to begin with (in which case you may need as much filtering to 
get a clean sine wave as if you started with an asymmetrical square 
wave), and many packaged oscillators have CMOS logic outputs (in 
which case you would have to break into the sealed package to get at 
any sine or sine-ish signal there may be).

Best regards,
