CMT2219B is an ultra-low power, high performance, OOK (G) FSK RF Receiver suitable for a variety of 140 to 1020 MHz wireless applications. It is part of the CMOSTEK NextGenRFTM RF product line. The product line contains the complete transmitters, receivers and transceivers. The high integration of CMT2219B simplifies the peripheral materials required in the system design. Up to -121 dBm sensitivity optimizes the performance of the application. It supports a variety of packet formats and codec methods to meet the needs of various different applications. In addition, CMT2219B also supports 64-byte Rx FIFO, GPIO and interrupt configuration, Duty-Cycle operation mode, channel sensing, high-precision RSSI, low-voltage detection, power-on reset, low frequency clock output, manual fast frequency hopping, squelch and etc. The features make the application design more flexible and differentiated. CMT2219B operates from 1.8 V to 3.6 V. Only 8.5 mA current is consumed when the sensitivity is -121 dBm, Super-low Power mode can further reduce the chip power consumption.
