hi,
I am making an ARM9 board that needed the crystals as shown
1)
18.432Mhz pack:3.2x2.5 mm e.g. ABM8-18.432MHZ-B2-T
2)
25 Mhz pack :MM20SS e.g.ECS-.327-12.5-17-TR
3)
32.768Khz pack : 3.2x2.5 e.g.ABM8-25.000MHZ-B2-T
these were not available in local market and digikey etc costed 5-6 times more
My changes
>>I bought local crystals as shown
1)18.432Mhz pack thru hole **broken link removed**
used with : AT91rm9200 atmel arm9 chip
2) 25 Mhz http://uk.farnell.com/productimages/farnell/standard/GE2HC494HSMX06-40.jpg
used with : ethernet controller chip
3)32.768Khz
**broken link removed**
used with :AT91rm9200 atmel arm9 chip
>I can manage to stick the crystals with superglue to some part of pcb
and join small wires to smd pads.
Question is will the substitution work.
