AS3933 - 3D Low Frequency Wake-Up Receiver

General Description

The AS3933 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 15-150 kHz.

The integrated correlator can be used for detection of a programmable 16-bit or 32-bit Manchester wake-up pattern.

Key Features

  • of AS3933 enable to optimize its settings for achieving a longer distance while retaining a reliable wake-up generation. The sensitivity level of AS3933 can be adjusted in presence of a strong field or in noisy environments. Antenna tuning is greatly simplified, as the automatic tuning feature ensures perfect matching to the desired carrier frequency. The device is available in 16-pin TSSOP and 16-LD QFN (4x4mm) packages, and DoW (dice on wafer). Ordering Information and Content Guide appear at.

AS3933 3D Low Frequency Wake-Up Receiver General Description The AS3933 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 15-150 kHz. The integrated correlator can be used for detection of a programmable 16-bit or 32-bit Manchester wake-up pattern. The device can operate using one, two, or three active channels. The AS3933 provides a digital RSSI value for each active channel, it supports a programmable data rate and Manchester decoding with clock recovery. The AS3933 offers an internal Clock Generator, which is either derived from a crystal oscillator or the internal RC oscillator. The user can decide to use the external clock generator instead.
