DA1016.003 31 October, 2000 MAS1016 AM Receiver IC *Wide Supply Voltage Range *Power Down and Power Up Control *Control for AGC On DESCRIPTION The MAS1016 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 APPLICATIONS * * * * * * Wide Supply Voltage Range Power Down Control Only a Few External Components Needed Highly Sensitive AM Receiver Control for AGC On Time Signal Receiver designed for MSF (British), WWVB (USA), JG2AS (Japan) and DCF77 (Germany) BLOCK DIAGRAM QO RFI QI AGC Amplifier AON (=AGC on) Demodulator & Comparator OUT Power Supply/Biasing VDD VSS PDN AGC DEC 1 (6) DA1016.003 31 October, 2000 PAD LAYOUT 1788 m VSS RFI PDN AON DEC 1786 m MAS1016 VDD QO QI AGC OUT DIE size = 1.79 x 1.79 mm; PAD size = 100 x 100 m Substrate is connected to Vdd.
