I have a 16f688 outputting music using the FREQOUT command. When I define the internal oscillator at 8 MHz the audio is slightly warbled and plays faster than I would like, but when I define the internal oscillator at 10 MHz, which is higher than the chips internal oscillator is rated for, the music plays exactly how I want it to.

My question is will this damage my chip? It seems to work alright and I'd like to keep the music this way. Or should I buy a 10 MHz crystal just to be safe?

Here is the datasheet: http://ww1.microchip.com/downloads/e...doc/41203d.pdf

Thanks guys,
