MAS1016B
AM Receiver IC
• High Sensitivity
• Very Low Power Consumption
• Wide Supply Voltage Range
• Power Down Control
• Control for AGC On
• High Selectivity by Crystal Filter
DESCRIPTION
The MAS1016B 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. WWVB in USA and JJY in
Japan require use of AGC control procedure, which
is simplified in MAS1016B.
FEATURES
• Highly Sensitive AM Receiver, 0.5 µV_RMS typ.
• Wide Supply Voltage Range from 1.1 V to 3.6 V
• Very Low Power Consumption 50 µA typ.
• Power Down Control
• Only a Few External Components Necessary
• Control for AGC On
• Wide Frequency Range from 40 kHz to 100 kHz
• High Selectivity by Quartz Crystal Filter
• Die and TSSOP-16 Package
APPLICATIONS
• Time Signal Receiver Designed for MSF (UK),
WWVB (USA), JJY (Japan) and DCF77
(Germany)
• Receiver for ASK Modulated Data Signals
