DA1016B.000c 4 January, 2002 MAS1016B AM Receiver IC Example implementation * * * * * * Antenna Receiver board Crystal This data sheet is preliminary and subject to change without notice. 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. 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. The control for AGC (automatic gain control) can be used to switch AGC on or off if necessary. FEATURES APPLICATIONS * * * * * * * * * Highly Sensitive AM Receiver, 0.5VRMS typ.

Ferrite antenna frequencies and recommended crystal frequencies are presented in table 1. For more details about crystal selection see DAEV1016B.

Recommended capacitor values are presented in table 2. WWVB and JJY systems require external control of AON (=AGC on) pin to receive pulses correctly. For more details about required control of AON in WWVB and JJY systems see DAEV1016B. The AGC and DCF capacitors should have low leakage currents due to very small 40nA signal currents through the capacitors.
