iMac crystal oscillator identification

[jason9v]

Hello,

I am making a presentation about the use of crystal oscillators in computers. There is an image of the motherboard of an iMac (late 2009 model, 21.5"), you can see it here:

and here:

(please ignore the red rectangle)

The oval-ish shaped, raised, silver colored component on the lower right of the images looks like an oscillator to me.

If that is indeed the oscillator, I was wondering if anyone can tell me specifically which oscillator it is? I would like to know the part number if possible (could it possibly be the HC-49?).

You can see more pictures of the iMac here:

KODAWARISAN?????????? (New iMac)?KODAWARISAN Mac?????????????????

Thank you to anyone who knows this.....

Jason

Jason,

It is a crystal, not an oscillator module. It is HC49/4H package I think. The frequency will be written on it.
