Default state when the radio is not

receiving or transmitting. Typ.

current consumption: 1.6 mA.

Lowest power mode. Most

Current consumption typ

400 nA, or typ 900 nA when

wake-on-radio (WOR) is

enabled.

All register values are

retained. Typ. current

consumption; 0.16 mA.

Used for calibrating frequency

synthesizer upfront (entering

receive or transmit mode can

then be done quicker).

Transitional state. Typ. current

consumption: 8.2 mA.

Frequency synthesizer is turned on, can optionally be

calibrated, and then settles to the correct frequency.

Transitional state. Typ. current consumption: 8.2 mA.

Frequency synthesizer is on,

ready to start transmitting.

Transmission starts very

quickly after receiving the STX

command strobe.Typ. current

consumption: 8.2 mA.

Typ. current consumption:

13.5 mA at -6 dBm output,

16.9 mA at 0 dBm output,

30.7 mA at +10 dBm output.

Typ. current

consumption:

from 14.4 mA (strong

input signal) to 15.4mA

(weak input signal).

Optional transitional state. Typ.

current consumption: 8.2mA.

In FIFO-based modes,

transmission is turned off and

this state entered if the TX

FIFO becomes empty in the

middle of a packet. Typ.

current consumption: 1.6 mA.

In FIFO-based modes,

reception is turned off and this

state entered if the RX FIFO

overflows. Typ. current

consumption: 1.6 mA.
