It is a part of the TM CMOSTEK NextGenRF family, which includes a complete line of transmitters, receivers and transceivers. The CMT2119A provides the simplest way to control the data transmission. The transmission is started when an effective SOT23-6 level turnover is detected on the DATA pin, while the t ransmission action will stop after the DATA pin holding level low for a defined time window, or after a two-wire interface (TWI) command is issued. The chip features can be 6 configured in two different ways: setting the configuration 1 VDD XTAL registers through the TWI, or programming the embedded EEPROM with CMOSTEK USB Programmer and the 5 RFO GND 2 RFPDK. The device operates from a supply voltage of 1.8 V to 3.6 V, consumes 27.6 mA (FSK 868.35 MHz) when transmitting +10 dBm output power, and only leak 20 nA DATA CLK 4 3 when it is in sleep state. The CMT2119A transmitter together with the CMT2219A receiver enables a robust RF link.
