Clock and control modules

Our clock and control modules for FSK technology have been developed to receive the ERC time signal. They guarantee reception in seconds. A big advantage is the automatic transmitter selection between DCF49 (Mainflingen in Germany), DCF39 (Burg in Germany) and HGA22 (Lakihegy in Hungary) which is enabled by the multi-band reception of the module.

The internal, automatically synchronized real-time clock can be accessed via the serial interface. There is a choice of two modules. Radio clock 1 (FUM1 FSK) issues a DCF77 compliant output signal, has a 300 bps interface and transitional compensation. The successor model radio clock 2 (FUM2 FSK) operates with a much faster interface of 4800 bps. It has high accuracy time of 5ms and the ability to retrieve the reception quality.

Both modules are suitable for battery operation. On request we deliver with pin connectors for a minimum quantity of 1000 pieces.
