CMT2220LYW

300 - 480 MHz OOK Receiver with 3.0 - 5.5 V Supply Power

CMT2220LY-.png

Description


The CMT2220LY are new-generation, low-power, high-performance, plug-and-play based OOK RF receiver with no need for register configuration, fitting for wireless

receiving applications within 300 - 480 MHz ISM band. The CMT2220LY supports a data rate range of 1 - 5 kbps, ideal for pairing with encoder or MCU based low-cost transmitters. Operating in a supply voltage range of 3.0 - 5.5 V, the chip remains stable receiving performance with no significant performance change in different power supply voltage within this voltage range. It consumes only a current of 5.7 mA while

achieving a receiving sensitivity of -110 dBm @ 433.92 MHz. The chip can operate at the commonly used 315 MHz frequency or other RF frequency points within the applicable

frequency band through selecting crystals with different frequencies. The CMT2220LY receiver cooperating with CMT211x / 5x / 8x transmitters can fulfill cost-effective RF

application solutions conveniently.
