Hey,
I am looking for 25MHz SMD crystal for my PIC18F board and I found that:

The product name says:
but there is no more description.
The image attached looks like this:
My question is, why is there 4 pins? Is this crystal somehow intnegrated with capacitors or what? But even integrated crystal with capacitors would have GND, OSC1, OSC2 pins - that's 3 pins and not 4....
