AS3932

AS3932 3D Low Frequency Wakeup Receiver General Description The AS3932 is a 3-channel low power ASK receiver that is able to generate a wake-up 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 wake-up 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. 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 a longer distance while retaining a reliable wake-up generation. The sensitivity level of AS3932 can be adjusted in presence of a strong field or in noisy environments. The device is available in 16-pin TSSOP and 16LD QFN (4×4) packages.
