Rev. 1.6
The 73M1x22 can:
Shift the characteristics by setting the turn-on voltage.
Enable a current limit of 42 mA.
The 73M1x22 meets a wide range of different countries’ requirements under software control. See Section
There are two operating states for the DC-IV circuits: Hold and Seize.

Figure 32: Tip-Ring Voltage versus Current Using Different DCIV Settings
The Hold state is the nominal operational point for the DC-IV circuits. The response shown in Figure 31 is
for the Hold state (both DC and AC transconductance circuits are enabled). The slope of the DC-IV
characteristics
is approximately 50 Ω when the series resistance of a typical PPTC resettable fuse is taken
into account.
The Seize state is a condition that is used by some central offices to determine an off-hook condition. In
this state an additional load is added to the nominal operational DC-IV characteristics used during the Hold
state
In the Seize state (only the DC transconductance circuit is enabled), the turn-on voltage is reduced on the
line independent of the DC-IV control bits. See the description of the DCIV bit in Section 11.6.
