Key Features
RF Performance
• High sensitivity (–111 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 +10
dBm for all supported frequencies
• Excellent receiver selectivity and blocking
performance
• Programmable data rate from 1.2 to 500
kBaud
• Frequency bands: 300-348 MHz, 387-464
MHz and 779-928 MHz
Analog Features
• 2-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: 90us settling time
• Automatic Frequency Compensation
(AFC) can be used to align the frequency
synthesizer to the received center
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 de-
whitening of data
Low-Power Features
• 400 nA sleep mode current consumption
• Fast startup time: 240us from sleep to RX
or TX mode (measured on EM reference
design [5] and [6])
• Wake-on-radio functionality for automatic
low-power RX polling
• Separate 64-byte RX and TX data FIFOs
(enables burst mode data transmission)
General
• Few external components: Completely on-
chip frequency synthesizer, no external
filters or RF switch needed
• Green package: RoHS compliant and no
antimony or bromine
• Small size (QLP 4x4 mm package, 20
pins)
• Suited for systems targeting compliance
with EN 300 220 (Europe) and FCC CFR
Part 15 (US).
• Support for asynchronous and
synchronous serial receive/transmit mode
for backwards compatibility with existing
radio communication protocols
