4.2. Digital Programmable Gain/Attenuation
See functional description sections of digital programmable gain/attenuation for guidelines on computing register
values. All values are represented in twos-complement format.
Note: The values of all indirect registers are undefined following the reset state. Shaded areas denote bits that can be read

and written but should be written to zeroes.
Receive Path Digital to Analog Converter Gain/Attenuation.
This register sets gain/attenuation for the receive path. The digitized signal is effectively mul-
tiplied by DACG to achieve gain/attenuation. A value of 0x00 corresponds to – ∞ dB gain
(mute). A value of 0x400 corresponds to unity gain. A value of 0x7FF corresponds to a gain
of 6 dB.
Transmit Path Analog to Digital Converter Gain/Attenuation.
This register sets gain/attenuation for the transmit path. The digitized signal is effectively
multiplied by ADCG to achieve gain/attenuation. A value of 0x00 corresponds to – ∞ dB gain
(mute). A value of 0x400 corresponds to unity gain. A value of 0x7FF corresponds to a gain
of 6 dB.
