CMT2220LSW
Advanced mixed-signal design on an independently innovated development platform.
300-480MHz
OOK Receiver

The CMT2220LS 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 CMT2220LS 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 -108 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 CMT2220LS receiver cooperating with CMT211x / 5x / 8x transmitters can fulfill cost-effective RF application solutions conveniently.
