13 / 88 page ![]() SN260 Electrical characteristics 13/88 4.6 RF electrical characteristics 4.6.1 Receive Table 7 lists the key parameters of the integrated IEEE 802.15.4 receiver on the SN260. Note: Receive measurements were collected with Ember’s EM260 reference design at 2440MHz. The Typical number indicates one standard deviation above the mean. Table 7. Receive characteristics Parameter Test conditions Min. Typ. Max. Unit Frequency range 2400 2500 MHz Sensitivity (boost mode) 1% PER, 20byte packet defined by IEEE 802.15.4 - 93 - 98.5 dBm Sensitivity 1% PER, 20byte packet defined by IEEE 802.15.4 - 92 - 97.5 dBm High-side adjacent channel rejection IEEE 802.15.4 signal at -82dBm 35 dB Low-side adjacent channel rejection IEEE 802.15.4 signal at - 82dBm 35 dB 2nd high-side adjacent channel rejection IEEE 802.15.4 signal at - 82dBm 40 dB 2nd low-side adjacent channel rejection IEEE 802.15.4 signal at - 82dBm 40 dB Channel rejection for all other channels IEEE 802.15.4 signal at - 82dBm 40 dB 802.11g rejection centered at + 12MHz or - 13MHz IEEE 802.15.4 signal at - 82dBm 40 dB Maximum input signal level for correct operation (low gain) 0dBm Image suppression 30 dB Co-channel rejection IEEE 802.15.4 signal at - 82dBm - 6 dBc Relative frequency error (2 x 40 ppm required by IEEE 802.15.4) - 120 + 120 ppm Relative timing error (2 x 40 ppm required by IEEE 802.15.4) - 120 + 120 ppm Linear RSSI range 40 dB |
