Which crystal?

[MrZammler]

Hi

can anyone tell me the part number of the crystal I need to drive a 50Mhz 68060 on a cyberstorm mk2?

Thanks

Cystals don't have part numbers, except perhaps ones assigned by manufacturer or vendor.

The only thing you need to know is the shape. Pin assignment and operation are standard.

Hum,
 if i remember correctly , a 100Mhz (dilithium?) should be sought (the oscillator crystal number being twice the board speed, i.e. 66mhz -> 33mhz)

PM  Redrumloa to see if he can help?

blob . . .dilithium wasn't in StarTrek :-)

This is true for 040 cpu's. 060's need a same speed crystal.

Hum,
tnx for correcton…

When I bought my MKII crystals (to experiment with overclocking), I asked for 14/4 Single DIP package, 3.3 v  and then just specified the frequencies I wanted.
I don't have part numbers, but I'm sure Framiga does  :-)

edit: also known as DIL-14 (or full size can). You need through-hole or leaded, not surface-mounted.
