Crystals/Resonators

I'm familiar with the resonator plugged into the side of my Stamp,
and I've seen how they can be plugged into a couple of inverters to
emit a usable clock pulse...
But can they be used free-standing, without the inverters, to provide
clocking to another component? I'd like to avoid another chip on my
board if not necessary. In this case, I'm clocking a serial in-to-pwm
out chip...

such as 2 or 3 PICS.

connecting the resonator?
If I take a free-standing resonator, 5v on one side, and ground the
middle, I don't get anything out the third pin. Are the inverters a
necessary part of this equation?

PICS. On 16 series PICS, I just connect the oscillator output to PIC pin 16
(OSC1/CLKIN), with both the PIC and oscillator GND pins on the same ground
plane. So the oscillator can be used with multiple PICS up to the CMOS
fanout current limit.

Hmmm, yep, but don't the PICS have a pair of pins intended for
connecting the resonator?
If I take a free-standing resonator, 5v on one side, and ground the
middle, I don't get anything out the third pin. Are the inverters a
necessary part of this equation?
