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 VSS. The printed

circuit

capacitance

has

also

to

be

taken

into

consideration. The V3020 in DIL 8 package, running with

an 8.2 pF crystal at room temperature, will be adjusted to

better

than

±1s/day

with

a

6.8

pF

capacitor.
