Note 20: Measured according to Bluetooth® Low Energy Test Specification RF-PHY.TS/4.0.1, section 6.4.1.
Note 21: Measured according to Bluetooth® Low Energy Test Specification RF-PHY.TS/4.0.1, section 6.4.2.
Note 22: Measured according to Bluetooth® Core Technical Specification document, version 4.2, volume 6, section 4.4. Published value is for n =
IXIT = 4 . IXIT = 5 gives the same results, IXIT = 3 gives results that are 5 dB lower.
Note 23: Measured according to Bluetooth® Core Technical Specification document, version 4.2, volume 6, section 4.2.
Note 24: Measured according to Bluetooth® Core Technical Specification document, version 4.2, volume 6, section 4.3. Due to limitations of the
measurement equipment, levels of -5 dBm should be interpreted as > -5 dBm.
Note 25: PRF = PRSSI(min) + LRES(RSSI) x RXRSSI[7:0] ± LACC(RSSI). Thanks to constant gain biasing of RF part in the receiver, the RSSI can
be used to estimate absolute power levels, rather than mere level changes. Even across the full temperature range the variation is limited.
Note 26: Measured according to Bluetooth® Low Energy Test Specification RF-PHY.TS/4.0.1, section 6.2.3.
Note 27: To activate the "Near Field Mode", program address 0x50002418 with the value 0x0030.
