Descriptions
The CMT2119A 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
CMT2119A 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 CMT2119A transmitter
together with the CMT2219A receiver enables a robust RF
link.
