Adjacent channel rejection corrected to 46 dB for + 5MHz (was 39 dB), 39 dB for –5
MHz (was 46 dB) 58 dB for +10 MHz (was 53 dB) and 55 dB for-10 MHz (was 57 dB).
“image channel” deleted in text for In band spurious reception.
Revision for reference [1] updated.
CSMA-CA added to abbreviations.
Schematic view of the IEEE 802.15.4 Frame Format corrected, address field 0 to 20
bits.
Changed blocking specifications to relate to EN 300 440 class 2.
Updated addresses for Chipcon offices.
Added section Operating Conditions.
Section RAM access: A6:0 (LSB).
IOCFG0.BCN_ACCEPT bit added and described in section Address recognition and
the IOCFG0 register.
The previous IDLE mode has been renamed to power down to be consistent with
other Chipcon data sheets. Three power modes defined: Voltage regulator off (OFF),
Power down (PD) (Voltage regulator enabled), IDLE (XOSC running) and used
throughout the document.

harmonic to –37dBm.
Table with Crystal oscillator component values corrected.
Link to reference [3] corrected.
Corrected spelling grammar and references to tables and figures.
Figure showing SmartRF Studio user interface included.
Added figure to describe pin activity during RXFIFO read out.
Added description on how to connect pins when not using internal regulator.
2004-03-22 Application circuits: Pin 20 and pin 37 connected to 1.8 V from VREG_OUT.
