H5C1 RTC crystal?

[BigSteve]

I have hunted and not found anything.

Can somebody confirm that the crystal I need for the real time clock IC (DS1315) is a 32.768khz 'tuning fork clock crystal' please?

The spec sheet indicates that is a typical value - but I am looking for the mythical C1 BOM!!

That's the frequency you need, though I'm not 100% sure of the footprint.

Sadly it looks like the osc got missed. I can't check until I get back home on Monday.

Yes. Its a small cylinder shape quartz crystal, 2mm x 6mm. I think I fitted a slightly larger (3mm x 8mm) but it's a snug fit.

Excellent - thanks for confirmation.

Perfect - I have a local supplier with stocked device - Length 6.09 x 1.92 diameter with 0.7mm centres for leads. Perhaps also salvageable from a clock/watch too!
