Abuot PCF8563T Output Clock

bluestyle · ‎03-23-2018

hello,

What is the rise time of PCF8563T,It works in the 32.768kHz? And what is the accuracy?

Since I did not find the corresponding information in the Data Sheet, but these parameters are quite important.

Best regards！

Hi,

For fosc accuracy is 0.2ppm,what is your point the 'rise time'?

Hi,

So you also want to know the rise time of output clock,right?

Hi，

Yes, because the chip I used has requirements for the rise time of the clock.

Hi,

This CLKOUT is open drain structure,the pull up resistor value will have an affect on rise time.

We don't have the detail information about it.
