Description

Receive Path Digital to Analog Converter Gain/Attenuation.

This register sets gain/attenuation for the receive path. The digitized signal is effectively multiplied 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.
