C-MAX
decrease the Q value of the circuit. They have the same effect like conducting plates close to the antenna.
To avoid undesired loops in the antenna circuit, it is recommended to mount the capacitor C
possible to the antenna coil or to use a twisted wire for the antenna-coil connection. This twisted line is also
necessary to reduce feedback of noise from the microprocessor to the IC input. Long connection lines must
be shielded.
A final adjustment of the time-code receiver can be carried out by pushing the coil along the bar antenna.
7.2 Dimensioning of capacitor C
The value of 22nF for capacitor C
frequency of 77.5 kHz. For lower frequencies (40kHz, 60kHz) a minimum value of C
used. For a better damping of noise and other interference it is recommended to double the values of C
That means C
done according to each application.
