8.1
µA Automatic RX polling once each second, using low-power RC
oscillator, with 460 kHz filter bandwidth and 250 kbps data rate,
PLL calibration every 4^th wakeup. Average current with signal in
channel below carrier sense level.
35
µA Same as above, but with signal in channel above carrier sense
level, 1.9 ms RX timeout, and no preamble/sync word found.
1.4
µA Automatic RX polling every 15^th second, using low-power RC
oscillator, with 460 kHz filter bandwidth and 250 kbps data rate,
PLL calibration every 4^th wakeup. Average current with signal in
channel below carrier sense level.
42
µA Same as above, but with signal in channel above carrier sense
level, 37 ms RX timeout, and no preamble/sync word found.
1.5
mA Only voltage regulator to digital part and crystal oscillator running
(IDLE state)
7.4
mA Only the frequency synthesizer running (after going from IDLE
until reaching RX or TX states, and frequency calibration states)
