APPLICATION HINT’S

The PCB has to be designed for RF conditions.

The ferrite antenna is a critical devices of the complete clock receiver.

The dimensioning of the antenna resonant resistance is a compromise between high

signal voltage and low antenna noise voltage. The Q-factor of antenna should be high

for attenuation of inference signal’s. In the application circuit is the Rref 100k,

Q=80.

To achieve a high selectivity the parasitic parallel capacitance of the crystal should be

1 ~ 1 . 5 p F.

For a trouble-free reception the capacitor on GND and CD3 have to be arranged nearby

the chip foot prints.
