Y-ellow Tim.
         Probably someone has already mentioned this but I'm writing this 
quickly in between outages as telstra are up to their old incompetent 
tricks again.

May I suggest looking into using a PLL frequency synthesizer type 
arrangement. The beauty of a PLL is that it kinda works like a VCO but 
(Well yes I know it's a VCO) but can be xtal locked. So you have a 
reference clock (The xtal) and any devisor down from them. Not just the 
usual divide by 2 or 3. And of course, it's variable.

It's not quite like having your cake and eating it too but it's close and 
for your app you could probably get away with one of those cheap-assed CMOS 
PLLs. I've used these a few times myself and found them to be more than 
adequate for audio.

Anyway. Hope that is some use to you. And hope I don't have to spend 
another 5 days waiting for telstra feed some peanuts to their monkeys so I 
can have my link back again.

Be absolutely Icebox.
