IN
A ferrite antenna is connected between IN and V
CC
. For
high sensitivity the Q of the antenna circuit should be as
high as possible, but a high Q often requires temperature
compensation of the resonant frequency. Specifications
are valid for Q > 30. An optimal signal to noise ratio will
be achieved by a resonant resistance of 50 to 200 k .

SB
A resistor R
SB
is connected between SB and GND. It con-
trols the bandwidth of the crystal filters. It is
recommended: R
SB
= 0
for DCF 77.5 kHz, R
SB
=
10 k for 60 kHz WWVB and R
SB
= open for JG2AS
40 kHz.
