AFE4960 EVM 32KHz clock accuracy?

Hello,

I've a question about 32KHz clock accuracy.

I use  Synchronous mixed clock mode for AFE4960 EVM board because of measuring  the high precision ECG data and using as timer counter.

 So I 'd like to know the accuracy of 32KHz external clock..

It looks like a ceramic oscillator...

Thanks,

Takayuki.
