Error! Reference source not found. suggests filter settings in FSK mode, along with the corresponding passive
filter bandwidth and the accepted tolerance on the crystal reference.
3.4.6. Channel Filters Setting in OOK Mode
The center frequency, fo, is always set to 100kHz. The following chart shows the receiver bandwidth when
changing RXParam_Butterfilt bits, whilst the polyphase filter is activated.

3.4.7. RSSI
After filtering, the In-phase and Quadrature signals are amplified by a chain of 11 amplifiers, each with 6dB gain.
The outputs of these amplifiers are used to evaluate the Received Signal Strength (RSSI).
3.4.7.1. Resolution and Accuracy
Whilst the RSSI resolution is 0.5 dB, the absolute accuracy is not expected to be better than +/- 3dB due to process
and external component variation. Higher accuracy whilst performing absolute RSSI measurements will require
additional calibration.
3.4.7.2. Acquisition Time
