Key Features

RF Performance

 High sensitivity

o -116 dBm at 0.6 kBaud, 433 MHz,

1% packet error rate

o -112 dBm at 1.2 kBaud, 868 MHz,

1% packet error rate

 Low current consumption (14.7 mA in RX,

1.2 kBaud, 868 MHz)

 Programmable output power up to +12

dBm for all supported frequencies

 Excellent receiver selectivity and blocking

performance

 Programmable data rate from 0.6 to 600

kbps

 Frequency bands: 300-348 MHz, 387-464

MHz and 779-928 MHz

Analog Features

 2-FSK, 4-FSK, GFSK, and MSK supported

as well as OOK and flexible ASK shaping

 Suitable for frequency hopping systems

due to a fast settling frequency

synthesizer; 75 μs settling time

 Automatic Frequency Compensation

(AFC) can be used to align the frequency

synthesizer to the received signal centre

frequency

 Integrated analog temperature sensor

Digital Features

 Flexible support for packet oriented

systems; On-chip support for sync word

detection, address check, flexible packet

length, and automatic CRC handling

 Efficient SPI interface; All registers can be

programmed with one “burst” transfer

 Digital RSSI output

 Programmable channel filter bandwidth

 Programmable Carrier Sense (CS)

indicator

 Programmable Preamble Quality Indicator

(PQI) for improved protection against false

sync word detection in random noise

 Support for automatic Clear Channel

Assessment (CCA) before transmitting (for

listen-before-talk systems)

 Support for per-package Link Quality

Indication (LQI)

 Optional automatic whitening and dewhitening

of data

Low-Power Features

 200 nA sleep mode current consumption

 Fast startup time; 240 μs from sleep to RX

or TX mode (measured on EM reference

design [1] and [2])

 Wake-on-radio functionality for automatic

low-power RX polling

 Separate 64-byte RX and TX data FIFOs

(enables burst mode data transmission)
