This bit may be written to a zero or one.
4FULL2
Enhanced Full Scale (2x) Transmit and Receive Mode.
0=Default
1 = Transmit/Receive 2x Full Scale
This bit changes the full scale of the ADC and DAC from 0 min to +6 dBm into 600
load (or
1.5 dBV into all reference impedances). When this bit is set, the DCV[1:0] bits (Register 26)
should be set to all 1s to avoid distortion at low loop currents.
3:0
ACIM[3:0]
AC Impedance Selection.
The off-hook ac termination is selected from the following:
0000 = 600
0001 = 900
0010 = 270
+ (750 || 150 nF) and 275 + (780 || 150 nF)
0011 = 220
+ (820 || 120 nF) and 220 + (820 || 115 nF)
0100 = 370
+ (620 || 310 nF)
0101 = 320
+ (1050 || 230 nF)
0110 = 370
+ (820 || 110 nF)
0111 = 275
+ (780 || 115 nF)
1000 = 120
+ (820 || 110 nF)
1001 = 350
+ (1000 || 210 nF)
1010 = 200
+ (680 || 100 nF)
1011 = 600
+ 2.16 F
1100 = 900
+ 1 F
1101 = 900
+ 2.16 F
1110 = 600
+ 1 F
1111 = Global impedance
For si3011 line-side device, always write bits 3:2 and bit 0 to zero.
