IC Receiver-CMT2219A


The CMT2219A is an OOK and (G) FSK receiver with ultra low consumption and high performance for various wireless applications from 300 to 960 MHz. All functions can be configured either by EEPROM programming offline or by writing online registries. The configuration file to be written to the registers is generated by the intelligent RFPDK. The CMT2219A works with a supply voltage of 1.8 V to 3.6 V; when it is lit, it only consumes 5.7 mA of current and offers a reception sensitivity of -109 dBm, and 60 nA standby. The device supports package management, the 32-byte FIFO.

The CMT2219A receiver associated with the CMT2119AW transmitter enables a powerful RF link.
