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.
