Available 32.768kHz directly connect to the pin XTAL32kp of DA14580?

Hi ,

My DA14580 adopted circuit has another chip that can out the clock 32.768kHz generated by it's own crystal 32.768KHz( 20ppm frequecny tolerance ).

I want to directly connect another chip's out clock to the pin XTAL32kp of the DA14580. And the pin XTAL32km set as no connection(floating).

Is this available?

Hi igotit,

If the external clock is following the spec for the XTAL32 clock, you can apply an external 32.768 KHz to pin Xtal32Kp and left the other floating.
