Description

The AK2124 bipolar monolithic integrated circuit receives and demodulates digital time signals emitted by time signal transmitters in the long-wave range. It is designed for low-current battery operation and can be switched in power-down mode. Due to the possibility of connecting two antennas a position-independent stable operation is guaranteed. The circuit is thus capable of the selective reception of various time signal transmitters.
