General specification

All the provided values are specified over the operational conditions (VDD and temperature)

according to the Bluetooth 1.1 and 1.2 specifications unless otherwise specified.

6.1

Receiver

To be compliant with the Bluetooth norm, an external RF filter is required to provide

minimum -17dB of attenuation in the band: 30MHz - 2000MHz and 3000MHz - 12.75GHz.

All specifications below are given at pin level and over temperature unless otherwise

specified.
