Nordic NRF905 single chip 433/868/915 mhz transceiver
Single chip 433/868/915 MHz Transceiver
nRF905 is a single-chip radio transceiver for the 433/868/915 MHz ISM band. The
transceiver consists of a fully integrated frequency synthesiser, receiver chain with
demodulator, a power amplifier, a crystal oscillator and a modulator. The
ShockBurstTM feature automatically handles preamble and CRC. Configuration is
easily programmable by use of the SPI interface. Current consumption is very low, in
transmit only 9mA at an output power of -10dBm, and in receive mode 12.5mA. Built
in power down modes makes power saving easily realizable
True single chip GFSK transceiver in a small 32-pin package (32L QFN 5x5mm)
ShockBurst mode for low power operation
Power supply range 1.9 to 3.6 V
Multi channel operation ETSI/FCC Compatible
Channel switching time <650 s
Extremely low cost Bill of Material (BOM)
Adjustable output power up to 10dBm
Carrier detect for "listen before transmit" protocols
Data Ready signal when a valid data packet is received or transmitted
Address Match for detection of incoming packet
Automatic retransmission of data packet
Automatic CRC and preamble generation
Low supply current (TX), typical 9mA @ -10dBm output power
Low supply current (RX), typical 12.5mA
