Hi,

As it states in the data sheet specification section - the value should be typically 10pf, however if the clock runs slow or fast then you can fit a higher or lower value capacitor within the range 5 to 25 pf to compensate.

By fast or slow we are talking of the odd second or two per week

So range for adjustment is too small, and sinfully work is small.
OK thanks!
