It is part of the CMOSTEK TM NextGenRF family, which includes a complete line of transmitters, receivers and transceivers. An embedded QFN16 (3X3) EEPROM allows the frequency, symbol rate and other features to be programmed into the device using the CMOSTEK USB Programmer and RFPDK. Alternatively, in stock products of 868/915 MHz are available for immediate demands with no need of EEPROM programming. The CMT2217A operates from a supply voltage of 1.8 V to 3.6 12 11 10 9 V, when it is always on, it consumes only 6 mA current while GND 8 XIN 13 achieving -109 dBm receiving sensitivity ( 9.6 ksps symbol RFIN 7 XOUT 14 r ate). It consumes even less power when working in GND 6 CLKO 15 duty-cycle operation mode via the built-in sleep timer. The device provides demodulated data, power-on reset output VDD 5 DOUT 16 as well as a system clock output for use by an external 1 2 3 4 microcontroller or decoder. CMT2217A receiver together with the CMT2117A transmitter enables an ultra low cost RF link.
