Time Code Receivers

MAS

MAS6181B Stand-alone Dual Band Time Signal AM Receiver IC with Differential Input

The MAS6181 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.

The MAS6181 supports receiving two different frequency signals by two selective crystal filters and an integrated switch to switch between two antenna frequencies. It has differential input for improved common mode disturbance rejection.

It’s also possible to use the MAS6181 in triple band applications.


MAS6180B Single Band Time Code Receiver IC - 1.1V - 3.6V

Only a few external components are required. The circuit has a preamplifier, wide range automatic gain control, demodulator and an 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.


MAS6180C Single Band Time Code Receiver IC - 1.5V - 5.5V

The MAS6180 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. The circuit has a preamplifier, wide range automatic gain control, demodulator and an 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.


Time Code Receiver Modules

We can now offer time signal receiver modules that comprises of a ferrite antenna and an AM receiver IC printed circuit board. The boards includes either a MAS6180B1 AM single channel receiver IC or the dual channel MAS6181B, accompanied with necessary filter crystal and capacitor components.  The modules can be used both for evaluation of the MAS6180 or MAS6181 receiver ICs as well as for mass production.
