詳細(xì)描述

MAS6181 AM 接收器芯片是一種高靈敏度、易于使用的 AM 接收器，專門用于接收 40 kHz 至 100 kHz 頻率范圍內(nèi)的時間信號。時間信號接收只需要很少的外部元件。該電路內(nèi)置前置放大器、寬范圍自動增益控制、解調(diào)器和輸出比較器。輸出信號可直接由附加數(shù)字電路處理，以從接收信號中提取數(shù)據(jù)。如有必要，AGC（自動增益控制）控件可用于打開或關(guān)閉 AGC。

MAS6181 支持通過兩個選擇性晶體濾波器和一個集成開關(guān)在兩個天線頻率之間切換來接收兩個不同頻率的信號。它具有差分輸入以改善共模干擾抑制。

MAS6181 也可以用于三頻應(yīng)用。

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.
