CMT2210AW

ultra low power, high performance, low-cost OOK stand-alone RF receiver 

The CMT2210AW is an ultra low power, high performance, low-cost OOK stand-alone RF receiver for various 300 to 480 MHz wireless applications.

Descriptions

The CMT2210AW is an ultra low power, high performance, low-cost OOK stand-alone RF receiver for various 300 to 480 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, symbol rate and other features to be programmed into the device using the CMOSTEK USB Programmer and RFPDK. Alternatively, in stock products of 315/433.92 MHz are available for immediate demands with no need of EEPROM programming. When the CMT2210AW is always on, it consumes only 3.8 mA current while achieving -114 dBm receiving sensitivity. It consumes even less power when working in duty-cycle operation mode via the built-in sleep timer. The CMT2210AW receiver together with the CMT211xW transmitter enables an ultra low cost RF link.

CMT2210LW

ultra low power, high performance, low-cost OOK stand-alone RF receiver 

The CMT2210LW is an ultra low power, high performance, low-cost OOK stand-alone RF receiver for various 300 to 480 MHz wireless applications.

Descriptions

The CMT2210LW is an ultra low-cost, low power, high performance OOK stand-alone RF receiver for 315/433.92MHz wireless applications. It is part of the CMOSTEK NextGenRFTM family, which includes a complete line of transmitters, receivers and transceivers. The CMT2210LW is a true plug-and-run device, no register configuration and manually-tune is required. The device operates at either 315 MHz or 433.92 MHz through selecting an 18.8744 MHz or 26 MHz crystal, the data rate is optimized to around 2.4 ksps which fits well with the low-end data encoder or MCU based transmitter. The CMT2210L operates from 1.8 V to 3.6 V, finely work till the end of most batteries’ power. It consumes 3.3 mA current while achieving -109 dBm receiving sensitivity at 315 MHz and consumes 3.8 mA current while achieving -108 dBm receiving sensitivity at 433.92 MHz. The SOP8 package is available for easier and lower-cost manufacturing. The CMT2210LW receiver together with the CMT211xW transmitter enables an ultra low cost RF link. For NextGenRFTM receivers with more flexibility, the user can use the CMT2210LW
