AS3933 LF RECEIVER IC

Programmable 3D LF Wake-up Receiver

The AS3933 is a 3-channel ASK receiver that generates a wake-up signal upon detection of a data signal with a carrier frequency in the range of 15 - 150 kHz. It can be used to wake-up active tags in RTLS, PKE and other similar tracking and access control systems.
