RADIO CONTROLLED RECEIVER IC
DESCRIPTION
The D6002 is a bipolar integrated straight
through receiver circuit in the frequency range
fro m 40kHz up to 200kHz with ASK modulation.
The IC receivers and demodulates time code
signals transmitted by DCF77,MSF , WWVB
and G2AS.
Th e devices is designed for radio controlled
clock applications with very high sensitivity.
Integrated functions as stand by mode and
co mple mentary output stages offer features for
universal applications.
The BIP2 technology makes all the above features possible for very low cost
applications.

If PON is connected to GND/Vcc the D6002 receiver is active/stand-by.
OD1
Data output 1
The output signal can directly decoded by a microprocessor.
The output OD1 is a PNP open collector stage with high active logic. Th e
connection with an external resistor of 100kΩ to GND is possible.
OD2
Data output 2
The ou tput OD2 is a NPN open collector stage with low active logic. The connection
with an external resistor of 100kΩ to Vcc is possible.

GND1
Gr ound 1
D6002
GND1 is the control ground potential for the comp lete ci rcuit. GND1 have to
connected to GND2/GND3.
GND2
Gr ound 2
The Pin GND2 is the ground potential for the RF amplifier and has to connected to
GND1.
GND3
Gr ound 3
The Pin GND3 is the ground potential for the Post amplifier and has to connected
to GND1.
STOP
AGC stop
If STOP is connected to GND/Vcc t he AGC circuit is off/on
CAGC
AGC capacitor
The Pin CAGC is connected to an external capacitor against GND. It is necessary
to generate the peak value of the de modulator output voltage signal. Th e peak value
controls the AGC.
CDEM
Demodulation capacitor
The Pin CDEM is connected to an external capacitor against GND. It is necessary
for the de modulation of the AM signal.
CD3
Decoupling capacitor C2
The Pin CD3 is connected to an external capacitor against GND. It is necessary for
the stab ility of the post a mplifier. The values of the external capacitor influence the
frequency response of the post amplifier.
