1.Features Operation Frequency: 315 / 433.92 MHz OOK Demodulation Data Rate: 1.0 - 5.0 kbps Sensitivity: -109 dBm (3.0 kbps, 0.1％ BER) Receiver Bandwidth: 330 kHz Large Signal Handling: 10 dBm Stand-alone, No External MCU Control Required No Register Configuration Required Low Power Consumption: 3.3 mA @ 315 MHz 3.8 mA @ 433.92 MHz RoHS Compliant SOP8 Package
2.Descriptions The CMT2210LC is a low power, high performance OOK stand-alone RF receiver for 315/433.92 MHz wireless applications. It is part of the CMOSTEK NextGenRFTM family, which includes a complete line of transmitters, receivers and transceivers. The CMT2210LC 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 a 19.7008 MHz or 27.1383 MHz crystal, the data rate is optimized to 1 - 5 kbps which fits well with the low-end data encoder or a MCU based transmitter. It consumes 3.3 mA current at 315 MHz and 3.8 mA at 433.92 MHz while achieving -109 dBm receiving sensitivity. The SOP8 package is available for easier and lower-cost manufacturing. The CMT2210LC receiver together with the CMT21xx transmitter enables an ultra-low cost RF link. For NextGenRFTM receivers with more flexibility, the user can use the CMT2210AW.
