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 NextGenRFTM 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.
