1. Descriptions of RF Transmitter IC CMT2110B:

The CMT2110/17B devices are ultra low-cost, highly flexible, high performance, single-chip OOK transmitters for various 315/434/868/915 MHz wireless applications. The CMT2110B covers the frequency range from 312 to 480 MHz while the CMT2117B covers the 624 to 960 MHz frequency range. They are part of the CMOSTEK NextGenRFTM family, which includes a complete line of transmitters, receivers and transceivers. With very low current consumption,the device modulates and transmits the data which is sent from the host MCU. The CMT2110/17B uses a 1-pin crystal oscillator circuitwith the required crystal load capacitance integrated on-chip to minimize the number of external components.The CMT2110/17B transmitter together with the CMT221x receiver enables an ultra low cost RF link.
