Please take a look at the remote control crystal oscillator ?

Knowing the basic of crystal oscillators helps users ask the right questions when choosing a device for their designs.
Recently, I read an article about crystal oscillator(to know more about the article, one can visit the website: http://www.apogeeweb.net/article/147.html), which talked about the functions and working principles of the crystal oscillator. I think this passage is very useful, and help me a lot when I studied the crystal oscillator.
In fact, now I am meeting a problem, which is about the following picture.
Is this active or passive? Can I replace it with another brand? What does 13.000 79.79 mean?
It makes me confused. So if you know the answer, could you please share it to me? Thanks a lot.

Looks like a 13MHz MEMS oscillator.  You get the same pinout and size, probably wouldn't be a problem to replace.

ok thanks a lot

To me this rather looks like a plain "passive" crystal or ceramic resonator. The two identical/similar capacitors at the traces that both lead to the two adjacent pins of the PLL / clock generator chip (or whatever the small QFN is) are the load caps of the resonator, hence no "active" oscillator. I may be wrong though...

You're right
