AS3933 3-Channel Low-Power Programmable ASK Receiv

ams’ AS3933 is a three-channel low power programmable ASK receiver. This receiver can generate a wake-up signal upon detection of a data signal with a carrier frequency in the range of 15 kHz to 150 kHz. It can be used to wake-up active tags in real time location systems (RTLS), passive keyless entry (PKE), and other similar tracking and access control systems. The AS3933 provides additional RSSI value for each active channel, it supports a programmable data rate and Manchester decoding with clock recovery. The receiver comes in 16-pin QFN or TSSOP package that has a temperature range of -40°C to +85°C. The AS3933 is perfect for wireless sensor, active RFID tags, and passive keyless entry applications.
