Overclock A3000 16Mhz to 25Mhz

I've read a bunch about people successfully overclocking 16Mhz A3000 to 25Mhz and I want to give it a try. What I don't know is what the exact type of oscillator is used in the A3000. I know I need 50Mhz one but I'm not sure what pinning I need.

Can anyone point me to a compatible one?

Anyone who has done this change did you socket the oscillator?

Thanks.
