mA TX at +11 dBm)

■ Programmable RX digital filter from 1 kHz to

800 kHz

■ Programmable channel spacing (12.5 kHz

min.)

■ Excellent performance of receiver sensitivity (-

118 dBm), selectivity, and blocking

■ Programmable output power up to +11 dBm

■ Fast startup and frequency synthesizer settling

time (6 µs)

■ Frequency offset compensation

■ Integrated temperature sensor

■ Battery indicator and low battery detector

■ RX and TX FIFO buffer (96 bytes each)

■ Configurability via SPI interface

■ Automatic acknowledgement, retransmission,

and timeout protocol engine

■ Address check

■ Automatic CRC handling

■ FEC with interleaving

■ Digital RSSI output

■ Programmable carrier sense (CS) indicator

■ Automatic clear channel assessment (CCA)

before transmitting (for listen-before-talk

systems). Embedded CSMA/CA protocol

■ Programmable preamble quality indicator

(PQI)

■ Link quality indication (LQI)

■ Whitening and de-whitening of data

■ Wireless M-BUS, EN 300 220, FCC CFR47 15
