Data Sheet AS3932 3 D L o w F r e q u e n c y Wa k e u p R e c e i v e r 1 General Description The AS3932 is a 3-channel low power ASK receiver that is able to generate a wakeup upon detection of a data signal which uses a LF carrier frequency between 110 - 150 kHz. The integrated correlator can be used for detection of a programmable 16-bit wakeup pattern. The device can operate using one, two, or three active channels. The AS3932 provides a digital RSSI value for each active channel, it supports a programmable data rate and Manchester decoding with clock recovery. The AS3932 offers a real-time clock (RTC), which is either derived from a crystal oscillator or the internal RC oscillator. The programmable features of AS3932 enable to optimize its settings for achieving [ ... ]
