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)
