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 µVRMS 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
