Description:

CMT2210LH is a low power, high performance OOK RF receiver, suitable for wireless applications with 315 / 433.92 / 868 / 915 MHz and nearby frequency points in a ISM band. The CMT2210LH is a real plug and play chip. The CMT2210LH operates in a band of 300 - 960 MHz. The change of RF frequencies can be fulfilled by selecting crystals with different frequencies. The crystal frequencies corresponding to different RF frequencies can be read from the RFPDK interface. This chip is capable of a data rate range of 0.5 – 40 kbps and it is optimized to 1 - 5 kbps as factory setting, ideal for pairing with the low-cost 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 in two voltage ranges , namely, 3.0 - 5.5 V and 2.0 - 3.6 V. When operating at 433.92MHz, the chip consumes only 4.5 mA current while achieving the receiver sensitivity of the -109 dBm. The CMT2210LH receiver, co-working with the CMT211x/5x receiver, can deliver cost-effective RF application solutions.
