Thanks Jerry: I already looked  at the datasheet and still couldn't see whether 
it needed sync.Idont think it does but was curious about the ref. input,also 
pins 1 and 3.When 3 is>1v,it will shut off or when pin 1<1.2 V,it will shut 
down also. Aside from those two conditions,I see it as a free-running device.

| Is this a free running osc. or does it get sync input? In other words,what
inputs aside from Vcc does the device require?
