Descriptions

The CMT2210/17AW devices are ultra low power, high

performance, low-cost OOK stand-alone RF receiver for

various 300 to 960 MHz wireless applications. The

CMT2210AW covers the frequency range from 300 to 480

MHz while the CMT2217AW covers the 300 to 960 MHz

frequency range. They are part of the CMOSTEK

NextGenRF

family, which includes a complete line of

transmitters, receivers and transceivers. An embedded

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 433.92/868.35 MHz are available for

immediate demands without the need of EEPROM

programming. When the CMT2210/17AW is always on, it

consumes only 3.8 mA current while achieving -113 dBm

receiving sensitivity. It consumes even less power when

working in duty-cycle operation mode via the built-in sleep

timer. The CMT2210/17AW receiver together with the

CMT211x transmitter enables an ultra low cost RF link.
