access.
According to IEEE 802.15.4 the ED measurement duration is 8 symbol periods. For frames
operated at higher data rates the automated ED measurement duration is reduced to 32 µs to
take the reduced frame length into account, refer to
page
During Frame Buffer read access the ED value is appended to the PSDU data, refer to
11.3.3 “High Data Rate Frame Buffer Access” on page
Receiver Sensitivity Control
The different data rates between PPDU header (SHR and PHR) and PHY payload (PSDU)
cause a different sensitivity between header and payload. This can be adjusted by defining sen-
sitivity threshold levels of the receiver. With a sensitivity threshold level set (register bits
RX_PDT_LEVEL > 0), the receiver does not receive frames with an RSSI level below that
threshold. Under these operating conditions the receiver current consumption is reduced by
about 500 µA, refer to
ter 12.8.4.
Enabling receiver sensitivity control with at least RX_PDT_LEVEL = 1 is recommended for the 2
Mb/s rate with a PSDU sensitivity of -89 dBm. In the case of receiving with the default setting of
RX_PDT_LEVEL, a high data rate frame may be detected even if the PSDU sensitivity is above
the received signal strength. In this case the frame is rejected.
A description of the settings to control the sensitivity threshold with register 0x15 (RX_SYN) can
be found in
Reduced Acknowledgment Timing
On higher data rates the IEEE 802.15.4 compliant acknowledgment frame response time of
192 µs significantly reduces the effective data rate of the network. To minimize this influence in

acknowledgment frame is 5 octets according to IEEE 802.15.4.
