1. Descriptions of RF Receiver IC CMT2210LCW:

The CMT2210LCW 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 CMT2210LCW 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. The CMT2210LCW operates from 1.8 V to 3.6 V, finely work till the end of most batteries’power. It consumes 3.3 mA current at 315 MHz and 3.8mA at 433.92 MHz while achieving -109 dBm receiving sensitivity.

The SOP8 package is available for easier and lower-cost manufacturing. The CMT2210LCW 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.
