13 Crystal Electrical Characteristics and Requirements
(continued)
At the third overtone frequency, f
3
, it is desirable to have the net impedance of the trap circuit (X
T
) equal to the im-
pedance of C
2
(X
C2
), i.e.,
Selecting C

For a capacitor,
For an inductor,
Solving for C

, and realizing that L

yields,
Hence, for C
2
= 10 pF, C
1
= 15 pF. Since the impedance of the trap circuit in this example would be equal to the
impedance of a 10 pF capacitor, the negative resistance and supply current curves for C
1
= C
2
= 10 pF at 40 MHz
would apply to this example.
Finally, solving for the inductor value,
For the above example, L

is 3.2
