Product data sheet
Table 15:
These bits control the additional gain of the baseband between 0 dB and 9dB
[1]
Table 16:
This bit controls the RF attenuation inside the LNA amplifier.
Table 17:
Table 18:
These bits force the inputs of the main loop charge pump. Thus the current and leakage
measurement could be done. This test could be used also to force the LC VCO at its maximum or
minimum tuning voltage.
