Antenna L1
The PCB has to be designed for RF conditions.
The ferrite antenna is a critical devices of the comp lete clock receiver.
The dimensioning of the an tenna resonant resistance is a comp ro mise between high
signal vo ltage and low antenna noise vo ltage. Th e Q-factor of an tenn a shou ld be high
for attenuation of inferen ce signal’s. In the application circuit is the Rref < 1 00k,
Q=80.
To achiev e a high selectivity the parasitic parallel capacitance of the crystal should be
1~1.5pF.
For a trouble-free reception the capacitor on GND and CD3 have to be arranged nearby
the ch ip foot prin ts.
