Figure 6. Simplified Linefeed Architecture for TIP and RING Leads
(Diagram illustrates either TIP or RING lead of a single channel)
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, VOC, and is
programmable from 0 to 63.3 V in 1 V steps. The
constant current region is defined by the loop current
limit, ILIM, 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, VOC, is offset from ground by a
programmable voltage, VCM, 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, VOV, 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, VBATL, to reduce total
power dissipation when driving short loop lengths.
