1.Descriptions of RF Transmitter IC CMT2210AW:

The CMT2110AW is an ultra low-cost, highly flexible, high performance, single-chip OOK RF transmitter IC for various 240 to 480 MHz wireless applications. It is part of the CMOSTEK NextGenRFTM family, which includes a complete line of transmitters, receivers and transceivers. The device only requires 1-wire interface for the external MCU or encoder to send in the data and control the transmission.

An embedded EEPROM allows the frequency, output power and other features to be programmed into the chip using the CMOSTEK USB Programmer and RFPDK. Alternatively, in stock products of 315/433.92 MHz are available for immediate demands with no need of EEPROM programming. The CMT2110AW uses a 1-pin crystal oscillator circuit with the required crystal load capacitance integrated on-chip to minimize the number of external components. The CMT2110AW receiver together with the CMT211x transmitter enables an ultra low cost RF link.
