Yes, I now own 10 crystals that look just like the one in that datasheet. It is larger than most 32 kHz crystals, but it is still too small. Since the design capacitive loading on these crystals is so small, I don't think that it's a good idea to s...

Thanks for the quick response Imen. I looked up almost a dozen crystals from Table 7 of that application note, and none of the crystals that I looked at is larger than 2 mm in any dimension. The pads on the MB110B board appear to be for a crystal w...
