The CMT2110A covers the frequency range from 240 to 480 MHz while the CMT2117A covers the 240 to 960 MHz frequency range. They are part of the CMOSTEK TM NextGenRF family, which includes a complete line of transmitters, receivers and transceivers. With very low SOT23-6 current consumption, the device modulates and transmits the data which is sent from the host MCU. 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 6 XTAL 1 VDD s tock products of 433.92/868.35 MHz are available for immediate demands without the need of EEPROM 5 GND 2 RFO programming. The CMT2110/17A uses a 1-pin crystal oscillator circuit with the required crystal load capacitance DATA CLK 4 integrated on-chip to minimize the number of external 3 components. The CMT2110/17A transmitter together with the CMT221x receiver enables an ultra low cost RF link.
