6.14.16.6 RX selectivity

RX selectivity with equal modulation on interfering signal18

14 Typical sensitivity applies when ADDR0 is used for receiver address correlation. When ADDR[1...7]

are used for receiver address correlation, the typical sensitivity for this mode is degraded by 3 dB.

15 Typical sensitivity applies when ADDR0 is used for receiver address correlation. When ADDR[1..7] are

used for receiver address correlation, the typical sensitivity for this mode is degraded by 3 dB.

16 As defined in the Bluetooth Core Specification v4.0 Volume 6: Core System Package (Low Energy

Controller Volume)

17 Equivalent BER limit < 10E-04

18 Desired signal level at PIN = -67 dBm. One interferer is used, having equal modulation as the desired

signal. The input power of the interferer where the sensitivity equals BER = 0.1% is presented
