The V3020 will run slightly too fast, in order to allow the user to

adjust the frequency, depending on the mean operating

temperature. This is made since the crystal adjustment can only

work by lowering the frequency with an added capacitor

between XO and V . The printed circuit capacitance has also

SS

to be taken in consideration. The V3020 in DIL 8 package,

running with an 8.2 pF crystal at room temperature, will be

adjusted to better than ±1 s/day with a 6.8 pF capacitor.
