TheCMT2219A is an ultra low power, high performance, OOK and (G)FSK receiver for various300to960 MHz wireless applications. Itispartof the CMOSTEK NextGenRFTMfamily, which includes a complete line of ransmitters, receivers and transceivers. All features can be configured either by off-line EEPROM programming or on-line registers writing. The configuration filetobe written into the registers isgeneratedby the smart RFPDK.The CMT2219Aoperates from a supply voltage of 1.8 V to 3.6 V,whenit is alwayson, it consumes only 5.7 mA current while achieving -109 dBm receiving sensitivity (FSK, 9.6 ksps symbol rate, 868.35 MHz), andonly60nA 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 externaldevice. CMT2219A receiver together with the CMT211xA transmitter enables a powerfulRFlink.
