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.
