Descriptions

The CMT2119AW is a high performance, highly flexible,

low-cost, single-chip (G)FSK/OOK transmitter for various

240 to 960 MHz wireless applications. It is a part of the

CMOSTEK NextGenRFTM family, which includes a complete

line of transmitters, receivers and transceivers. The

CMT2119AW provides the simplest way to control the data

transmission. The transmission is started when an effective

level turnover is detected on the DATA pin, while the

transmission 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

configured in two different ways: setting the configuration

registers through the TWI, or programming the embedded

EEPROM with CMOSTEK USB Programmer and the

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

when it is in sleep state. The CMT2119AW transmitter

together with the CMT2219AW receiver enables a robust

RF link.
