It is part of the CMOSTEK TM NextGenRF 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 12 11 10 9 CMT2219A operates from a supply voltage of 1.8 V to 3.6 GND 8 XIN 13 V, when it is always on, it consumes only 5.7 mA current RFIN 7 XOUT 14 while achieving -109 dBm receiving sensitivity (FSK, 9.6 ksps symbol rate, 868.35 MHz), and only 60 nA sleep GND 6 GPO3 15 current for superior battery life. The device supports packet VDD 5 GPO4 16 handling, 32-byte FIFO, Manchester decoding and data 1 2 3 4 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 CMT2219A Top View configurable interrupts for the external device. CMT2219A receiver together with the CMT211xA transmitter enables a powerful RF link.
