Descriptions

The CMT221xB/LB device is an ultra-low power, high

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

various 300 to 920 MHz wireless applications. It is part of

the CMOSTEK NextGenRF

family, which includes a

complete line of transmitters, receivers and transceivers. An

embedded EEPROM allows the frequency, data 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 MHz is available for

immediate demands without the need of EEPROM

programming. When the CMT221xB/LB 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 CMT221xB/LB receiver together with the

CMT211x transmitter enables an ultra-low cost RF link.
