CMT2210LH is a low power, high performance OOK RF receiver


CMT2210LH is a low power, high performance OOK RF receiver. It is suitable for ISM band 315MHz/433.92MHz wireless applications. The CMT2210LH is a real plug and play chip without the register configuration or manual  tuning.  By  selecting  19.7029MHz  or 27.1412MHz crystal, the chip can operate at 315MHz or 433.92MHz. This chip supports the symbol rate range of 1~5 Kbps and is ideal for pairing with the low end transmitter based on the encoder or MCU. By selecting the VDD5V pin and VDDL pin open circuit or short circuit on the PCB, the CMT2210LH can operate at two voltage ranges of 3.0V-5.5V or 2.0V-3.6V. When the chip operates at 433.92MHz, the receiver sensitivity of the -109dBm can be achieved with only 4.5mA current. The device is packaged in SOP8 to facilitate the simple and low cost manufacturing.
