Hello, I am laying out a design in EAGLE which, like the IOT design, uses the Bosch sensors and the 14583.
I have been trying to figure out what the best crystals are for the 16M and 32k crystals. I have looked at some
reference designs (none of which are for the 14583 specifically but for say the 14580), and they seem to be
using a range of crystals relative to the allowed amount of load capacitance. For instance, designs are using
the Abracon ABS06-32.768kHz at multiple load capacitance ratings around 9 and 12.5 pF, in addition the load capacitance
values in the 16 MHz crystal are also varying in the designs with most people using the NDK NX2520SA at 7 to
10 pF load capacitance. I don't see a BOM for the IOT module so I'm not sure exactly what is used there which I would
really like to know. Can you give me some guidance here? Your crystal writeup AN_B_009 states that load capacitance
should be 6 pF for the 32k crystal and 10 pF for the 16M crystal which again is different from what others are using
but then again this seems to be aimed at the DA14580 and I am using the DA`4583 (assuming there is a difference in
the required crystals). As you can see I need input! Which crystals are correct for the DA14583. Thanks. Craig
