Note 1. Tx Data is assumed small enough that the combination of Tx Data and TXDG is less than 1.25 dBm.
8.8.1.2 Receive Gain Scaling
On the receive side, a 0 dBm receive signal on the line results in ~0 dBm at the PCM interface.
Means is provided to adjust receive signal path gain by use of a digital gain stage. This gain value is
controlled by Register 0x09[7:0] (RXDG). The gain values are explained in Table 33.
The two RXG bits (Register 0x14[1:0]) control the value of the receiver analog gain. The RXG bits must
be set to 10 to enable 0 dB gain in the receive path.
For the best S/N performance it is recommended to use a gain value up front in the analog domain. The
digital control should be used to fine-tune the receiver signal path gain.
When the received line signal exceeds a voltage level greater than specified by ITU-T
Recommendation G.711, the receive gain must be reduced to prevent saturation and clipping within
the receive signal processing path.
