General specification

All the values are provided according to the Bluetooth specification V2.1 + EDR (“Lisbon”)

unless otherwise specified. The below values are preliminary and will be updated in the next

version of this datasheet.

6.1

Receiver

All specifications below are given at device pin level and with the conditions as specified.

Parameters are given for each of the 3 modulation types supported.

Typical is defined at Tamb = 25 °C, BT_HV = 2.75 V. Minimum and Maximum are worst cases

over corner lots and temperature. Parameters are given at device pin, except for receiver

interferers measured at antenna with a filter having a typical attenuation of 2.3 dB.
