I am working on making a PCB and the one I am using as a model uses this crystal on the ATMEGA644PA…
I am used to seeing a metal oblong type package.
What is the smallest package this crystal comes in? I am also using a pre-made microcontroller breakout board that already has a crystal on it. Super tiny. I’d remove that one and put another one on matching the specs of the one in the picture.
Nice. I just had to sort by cheapest price.
So, the one in the picture is 3 ‘pin’ well, 6, but the other 3 are passthru it seems.
Why this type instead of the ‘can’ type? Does this type have the caps inside?
1.62mmx2mm is a bit too small but thanks for getting me in the ballpark, I can find something from here.
No idea why or what it might contain without a part number, or a schematic showing how it is connected.
Well, the vias are ground, the traces go straight to Cry1 and Cry2 pins.
I guess this is a 2 parter question. First, identify. Looks like a 20Mhz crystal with caps. (guessing it has caps)
Second, looking to replace the existing crystal on the cpu breakout board I am using. That is the small one. I need to measure it.
Third, how the heck am I going to replace this little thing.
Replace it? Hot air rework station would work best.
Yeah that worked out well.
For the record, the crystal used is 3SMD package,
I used - Murata Electronics CERALOCK CSTNE series, CSTNE20M0V530000R0
