This device is billed as "Extremely Accurate" and with stability +-2ppm (at 0 to 40C). Everything
I've read in the data sheet - features as well as stability - fills the bill for my uses. However,
having read several reports in the past about poor stability of DS32KHZ (accurate 32KHz source), I
feel somewhat wary about the claims made for DS3231. Yes, I could just run some tests... but this
is no jelly bean; DigiKey gets US$7+ apiece in singles. Getting samples seems to be out of the
question; Dallas has never sent samples of anything I requested, presumably because I am not a
company.
So, does anyone here have first-hand experience with DS3231 and care to share? I'd be interested
to hear about:
1) short/long-term stability
2) accuracy
3) ease/difficulity/impossibility of synching the RTC's Freq-Out to a primary timing source's Second
pulse.
4) any functional characteristics that were unexpected, anomalous.
