Component recommendation(s) for the nRF52832-CIAA's 32.768kHz crystal?

[landon.ivy]

The provided reference circuit's BoM doesn't give exact part numbers for any of the components, including the 32.768kHz crystal oscillator (Designator: X2; Footprint: XTAL_2012).

Can you please provide a couple of options which are known to work best with the nRF52832-CIAA?

Hi there,

FC-135 32.768KHZ ±20PPM,9.0PF is the one that we use on our devkit,

Hi Jared, thanks for the quick response. I already settled on the much smaller ECS-.327-9-1210-TR. The only difference I can see is that the ESR (Equivalent Series Resistance) is 20 kOhms higher than yours (70 kOhms). Do you think it has a good chance of working well?

Hi there,

That looks ok, anything under 100 kohm is acceptable,

Jared
