DESCRIPTION
The MAS1017 AM-Receiver chip is a highly
sensitive, simple to use AM receiver specially
intended to receive time signals in the frequency
range from 40 kHz to 100 kHz. There are only a few
external components needed. The circuit has a
preamplifier, wide range automatic gain control,
demodulator and output comparator built in. The
output signal can be processed directly with an
additional digital circuitry to extract the data from the
received signal.
