It is a part of the HOPERF NextGenRF TM family, which includes a complete line of transmitters, receivers and transceivers. The RFM119W/RFM119SW 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 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 RFM119W/RFM119SW transmitter together with the CMT2219A receiver enables a robust RF link. RFM119W RFM119SW

Working States and Transmission Control Interface The RFM119W/S has following 4 different working states: SLEEP, XO-STARTUP, TUNE and TRANSMIT. SLEEP When the RFM119W/RFM119SW is in the SLEEP state, all the internal blocks are turned off and the current consumption is minimized to 20 nA typically. XO-STARTUP After detecting a valid control signal on DATA pin, the RFM119W/RFM119SW goes into the XO-STARTUP state, and the internal XO starts to work. The valid control signal can be a rising or falling edge on the DATA pin, which can be configured on the RFPDK. The host MCU has to wait for the tXTAL to allow the XO to get stable. The tXTAL is to a large degree crystal dependent. A typical value of tXTAL is provided in the Table 11. TUNE The frequency synthesizer will tune the RFM119W/RFM119SW to the desired frequency in the time tTUNE. The PA can be turned on to transmit the incoming data only after the TUNE state is done, before that the incoming data will not be transmitted. See Figure 16 and Figure 17 for the details. TRANSMIT The RFM119W/RFM119SW starts to modulate and transmit the data coming from the DATA pin. The transmission can be ended in 2 methods: firstly, driving the DATA pin low for tSTOP time, where the tSTOP can be configured from 20 to 90 ms on the RFPDK; secondly, issuing SOFT_RST command over the two-wire interface, this will stop the transmission in 1 ms. See Section 6.2.3 for details of the two-wire interface.
