Subject: Can I use an Epson SG-531P oscillator with a 16F84 PIC ...


Hi,

I'm looking at my first PIC project, and need some advice
on the following.

Rather than fooling around with a discrete crystal and a
pair of caps for my oscillator circuit, can I just use a
pre-packaged oscillator, like the Epson SG531-P line,
with the OUT (pin 5) connected directly to OSC1 on the
PIC?

The PIC datasheet for the 16F8X parts (DS30430c, pg. 40),
in figure 8-4, shows "clock from ext. system" going through
an inverter before connecting to OSC1.  What's the purpose
of this inverter?

Sorry if these questions are simple, but I'm a relative
newbie with digital circuits.

Thanks,

John
