4.3. DC Feed Characteristics
The Si3232 offers programmable constant voltage and
constant current operating regions as illustrated in
Figure 7 and Figure 8. The constant voltage region is
defined by the open-circuit voltage, V
OC
, and is
programmable from 0 to 63.3 V in 1 V steps. The
constant current region is defined by the loop current
limit, I
LIM
, and is programmable from 18 to 45 mA in
0.87 mA steps. The Si3232 exhibits a characteristic dc
impedance of 320
during Active mode.
The TIP-RING voltage, V
OC
, is offset from ground by a
programmable voltage, V
CM
, to provide sufficient
voltage headroom to the most positive terminal
(typically the TIP lead in normal polarity or the RING
lead in reverse polarity) for carrying audio signals. A
similar programmable voltage, V
OV
, is provided as an
offset between the most negative terminal and the
battery supply rail for carrying audio signals. (See
Figure 7.) The user-supplied battery voltage must have
sufficient amplitude under all operating states to ensure
sufficient headroom. The Si3200 may be powered by a
lower secondary battery supply, V
BATL
, to reduce total
power dissipation when driving short loop lengths.
