Analog gain
Digital gain
Analog gain: 4-bit front-end AGC analog gain setting
Digital gain: 4 MSBs of 6-bit front-end AGC digital gain setting
The product of the analog and digital gain is as follows:
Gain Product = (1 + 3 × analog_gain / 15) × (1 + gain_step × digital_gain / 4096)
Where,
0
≤ analog_gain ≤ 15
0
≤ digital_gain ≤ 63
The gain_step setting as a function of the analog_gain setting is shown in Table 3-15.
