MAS9180
AM Receiver IC
• Single Band Receiver IC
• High Sensitivity
• Very Low Power Consumption
• Wide Supply Voltage Range
• Power Down Control
• Control for AGC On
• High Selectivity by Crystal Filter
• Fast Startup Feature
DESCRIPTION
The MAS9180 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. Only a few external components are required for
time signal receiver. The circuit has preamplifier, wide
range automatic gain control, demodulator and output
comparator built in. The output signal can be
processed directly by an additional digital circuitry to
extract the data from the received signal. The control
for AGC (automatic gain control) can be used to switch
AGC on or off if necessary.
MAS9180 has both differential and asymmetric input
options and also options for compensating shunt
capacitances of different crystals (See ordering
information on page 15).

• Wide Frequency Range from 40 kHz to 100 kHz
• High Selectivity by Quartz Crystal Filter
• Both Differential and Asymmetric Input Versions
• Crystal Compensation Capacitance Options
APPLICATIONS
• Single Band Time Signal Receiver WWVB (USA),
JJY (Japan), DCF77 (Germany), MSF (UK), HGB
(Switzerland) and BPC (China)
