Hi,
I have a 32,768hz crystal but I am having trouble understanding it's inherit characteristics..
a) What is the simplest way to utilize this two lead device?
I've included an image of the datasheet and a Pierce oscillator
b) Is the waveform produced dictated by the crystal physics and/or the feedback network? In other words do I NEED circuits like the piece oscillator to produce waveform X or does the crystal output something when an AC or DC voltage is applied?
c) My component specifies a drive current of 1uW but doesn't list a voltage.. and some resources reveal that too high a voltage distorts the signal.. what's going on here?
If someone could clear up the basics that would be great, many resources I've read become specific to an application quickly and my brain is not that big.. my goal is a Real Time Clock using discreet components.
Thanks
