DCF77 Receiver Module Radio Time Module Radio Clock Radio Module Antenna

describe:

DCF receiver module with DCF antenna tuned to time signal transmitter DCF77 (Frankfurt 77.5 kHz). The antenna induction signal is sent to the IC for amplification, demodulation, and then identified by the MCU, so that the date and time of the timing center can be completely consistent.

Below you will find important setup and circuit diagrams.

⇒ DCF receiver module with antenna

• connect:

⇒ Ground = Pin G

⇒ Operating Voltage = Pin V

⇒ data = pin T

⇒ Power On/Off = Pin P1

⇒ 40/60K frequency selection = SEL

⇒AGC(Note 4: Optional Control for AGC On/Hold

AON control pin has internal pull up which turns AGC circuit on all the time if AON pin is left unconnected.

Optionally AON control can be used to hold and release AGC circuit. Stepper motor drive of analog clock or

watch can produce disturbing amount of noise which can shift the input gain to non optimal level. This

can be avoided by controlling AGC hold (AON=VSS) during stepper motor drive periods and releasing AGC

(AON=VDD) when motors are not driven. The AGC should be in hold only during disturbances and kept on other

time released since due to leakage the AGC can still change slowly when in hold.)

• Important note:

⇒ PIN P1 is an on/off switch and must be set to logic low.

Note: Single-frequency modules cannot be switched between different frequencies of DCF/WVB/HBG/BPC, JJY dual-frequency modules can be switched between 40K/60K two frequencies, to make a certain single-frequency module, only can receive signals in this frequency band.
