DCF77 Funkuhr Empfänger (Atomic Clock Receiver) 77.5kHz for Europe

Description

NEW version V4 available!

(Looking for the old version? Click here!)

A 77.5kHz DCF77 Atomic Clock Receiver is a device that receives the time signals transmitted by the German Physikalisch-Technische Bundesanstalt in Mainflingen. The receiver decodes the AM transmission to synchronize the time and date on atomic clocks, which are accurate to within a few microseconds. DCF77 broadcasts time signals on a frequency of 77.5kHz and provides a continuous, reliable source of time for most parts of Europe.

Our DCF77 Atomic Clock AM Receiver module for 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 MAS6180 from Micro Analog Systems (Finland). This module is in particular designed for use with microcontrollers in an operating voltage range of 3.3 or 5V.

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

Features

– operating voltage range 2V to 5.5V
– 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
– dimensions 25 x 20mm (18% smaller than V2)

The kit needs soldering: Crystal, antenna, and pin header are not factory assembled.

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

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.
