1 / 10 page  1 (10) DA6179.000 22 January, 2007 MAS6179 AM Receiver IC • Tri 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 MAS6179 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 receiving. 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. MAS6179 supports up to three frequency band operation by switching between three crystal filters and two additional antenna tuning capacitors. MAS6179 has differential input and two internal compensation capacitor options for compensating shunt capacitances of different crystals (See ordering information on page 10). FEATURES APPLICATIONS • Tri Band Receiver IC • Highly Sensitive AM Receiver, 0.4 µVRMS typ. • Wide Supply Voltage Range from 1.1 V to 3.6 V • Very Low Power Consumption • Power Down Control • Fast Startup • 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 • Differential Input • Multi Band Time Signal Receiver WWVB (USA), JJY (Japan), DCF77 (Germany), MSF (UK), HBG (Switzerland) and BPC (China) BLOCK DIAGRAM AGC Amplifier Power Supply/Biasing Demodulator & Comparator RFIM RFI2 VDD VSS PDN1 AGC DEC OUT QO3 QI AON QO1 QO2 RFI3 PDN2 RFIP VDD VDD This is preliminary information on a new product under development.
