DCF77 Empfänger Funkuhr Receiver 77.5kHz for Europe

Description

Overview

CANADUINO DCF77 Empfänger (English: Receiver) V3 for 60kHz and 77.5kHz is the most advanced and best-equipped AM Atomic Clock Receiver module for DIY projects available.

We designed this product around the awesome receiver chip from Micro Analog Systems (Finland). This module is in particular designed for use with microcontrollers in an operating voltage range of 2 to 15V, and standard logic levels 3.3 / 5V.

The kit includes a high-quality, fine-tuned 77.5kHz antenna with a Q-factor of at least 100.

The CANADUINO DCF77 Empfänger only works in middle Europe where the 77.5kHz signal can be received.

Features

The advantages compared to other modules:
– wide operating voltage range 2* to 15V
– 60 mm tuned high-gain, high-Q antenna
– current consumption <100µA (LEDs off)
– super high sensitivity of 0.4V (RMS)
– power down control pin
– fast start-up
– AGC control on/off

This kit needs some soldering. Crystal, antenna, and pin header are not assembled for more flexible use. So is it possible to use a different crystal and different antenna, for example for a 40kHz setup for Japan, or a DCF77 setup for Europe.

Downloads and Documentation

If you don’t want to develop your own project, you can find many projects online, using DCF77 Empfänger.

From Arduino data logger to Nixie Tube clocks. There are also libraries for Arduino IDE and other development sources online.

We highly recommend reading the official Wikipedia article about DCF77 time signal.

Download a detailed datasheet for the MAS6180C receiver IC that we use on our DCF77 Empfänger module.

* The module will work as expected with a voltage of as low as 2V. But the LEDs might not work as expected. We recommend a minimum voltage of 3V.

Notes

We did not publish a manual for V3 since the differences from the predecessor V2 are only minimal.
