Bit Name Function
7FULLFull Scale.
0 = Si3015 ADC/DAC full scale > –1 dBm.
1 = Si3015 ADC/DAC full scale > 3.2 dBm.
This bit changes the full scale of the ADC and DAC from –1 dBm min. to 3.2 dBm min. In
order to use this bit, the R2 resistor must be changed from 402
Ω to 243 Ω and ACT
(SF5, bit 4) must be set to 0. This bit is intended for use only in voice communications
and may be used in PCM modes.
6DCTO
DC Termination Off.
0 = Normal operation. The OFF bit must always be set to 0 when on-hook.
1 = DC termination disabled and the device presents an 800 Ω dc impedance to the line
which is used to enhance operation with an off-hook parallel phone.
5OHS
On-Hook Speed (See Table 13 and “Appendix A—DAA Operation”).
0 = The Si2400 will execute a fast on-hook.
1 = The Si2400 will execute a slow, controlled on-hook.
4ACT
AC Termination (See Table 13 and “Appendix A—DAA Operation”).
0 = Real impedance.
1 = Complex impedance.
3:2 DCT
DC Termination Voltage (See Table 13 and “Appendix A—DAA Operation”).
00 = Low Voltage Mode (transmit level = –5 dBm).
01 = Japan mode (transmit level = –3 dBm).
10 = USA mode (transmit level = –1 dBm).
11 = CTR21/France current limit mode (transmit level = –1 dBm).
1RZ
Ringer Impedance.
0 = Maximum (high) ringer impedance.
1 = Synthesize ringer impedance.
0RT
Ringer Threshold Select.
Used to satisfy country requirements on ring detection. Signals below the lower level will
not generate a ring detection; signals above the upper level are guaranteed to generate
a ring detection.
0 = 11 to 22 VRMS.
1 = 17 to 33 V
RMS
