Description
RF Performance
- High sensitivity (?111 dBm at 1.2k Baud, 868 MHz, 1% packet error rate)
- Low current consumption (14.7 mA in RX, 1.2k Baud, 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 500k Baud
- Frequency bands: 300-348 MHz, 387-46 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 centre frequency
- Integrated analogue 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 start-up time: 240us from sleep to RX or TX mode
- Wake-on-radio functionality for automatic low-power RX polling
- Separate 64-byte RX and TX data FIFOs (enables burst mode data transmission)
