DCV[1:0]
TIP/RING Voltage Adjust. Si3018 and Si3019 line-side only.
These bits adjust the voltage on the DCT pin of the line-side device, which affects the TIP/
RING voltage on the line. Low-voltage countries should use a lower TIP/RING voltage. Rais-
ing the TIP/RING voltage can improve signal headroom.

3.5 V
For Si3011 line-side device, the only valid setting for DCV[1:0] is 10.
5:4
MINI[1:0]
Minimum Operational Loop Current. Si3018 and Si3019 line-side only.
Adjusts the minimum loop current at which the DAA can operate. Increasing the minimum
operational loop current can improve signal headroom at a lower TIP/RING voltage.

Reserved
These bits must always be written to 0.

ILIM
Current Limiting Enable.
0 = Current limiting mode disabled.
1 = Current limiting mode enabled. This mode limits loop current to a maximum of 60 mA per
the TBR21 standard.
0
DCR
DC Impedance Selection.
0=50
dc termination is selected. This mode should be used for all standard applications.
1 = 800
dc termination is selected.
