Hi community,

 

I'm crashing my head against the wall to select the correct crystal oscillator from Netduino design. I designed my custom Pcb board derived from Netduino and then I need to buy a crystall oscillator. Does anyone has vendor URL at hand where I can order the 18.432 Mhz crystall oscillator in US? I google up and there are too many different configurations for this type of crystal and variety of manufactures then things start to be confusing for me.

 

Thanks in advance for any help

isent it 25mhz ?

[ziggurat29]

my schematic shows 25mhz, are you talking about the older Atmel based board?
The NP2 seems to use one like this:

Have you made your boards already?  could you not use something like this with a similar pad style

or this, much cheaper but different pad style

Thanks NooM and ziggurat29 for your help here, yes I'm using the old Netduino 1 schematics version. I sent my board to be manufactured without double checking the crystal thing and discovered that I selected through hole style versus SMD which would make life easier to find appropriate crystal but harder to solder on it. Since I cannot get the benefit of the pad configurations, darn!!!, I chose 3 different packages to be sent from mouser. They were derived from above hints so I greatly appreciate the help from the community.

The crystal is ABM7-18.432MHZ-10-D2Y-T by Abracon (ABM7 series datasheet), in single quantities available at Digikey (535-9841-1-ND), Mouser (815-ABM7-18.4-D2Y-T).
