• CMT2219AW-EQR RF Receiver IC

1. Descriptions of RF Receiver IC CMT2219AW:

The CMT2219AW is an ultra low power, high performance, OOK and (G)FSK RF receiver for various 300 to 960 MHz wireless applications. It is part of the CMOSTEK NextGenRFTM family, which includes a complete line of transmitters, receivers and transceivers. All features can be configured either by off-line EEPROM programming or on-line registers writing. 

The configuration file to be written into the registers is generated by the smart RFPDK. The CMT2219AW operates from a supply voltage of 1.8 V to 3.6V, when it is always on, it consumes only 5.8 mA current while achieving -109 dBm receiving sensitivity (FSK @9.6ksps symbol rate), and only 60 nA sleep current for superior battery life. 

The device supports packet handling, 32-byte FIFO, Manchester decoding and data de-whitening for the received data processing. Besides the demodulated data and the sync clock, the device can also send out the power-on reset, the system clock, as well as 2 configurable interrupts for the external device. CMT2219AW receiver together with the CMT211xAW transmitter enables a powerfulRF link.
