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.
FEATURES
• Wide Supply Voltage Range
• Power Down and Power Up Control
• Only a Few External Components Needed
• Highly Sensitive AM Receiver
APPLICATIONS
• Time Signal Receiver (designed for DCF77)
