2.1.9. Linefeed Calibration
An internal calibration algorithm corrects for internal and
external component errors. The calibration is initiated by
setting the CAL bit in direct Register 96. Upon
completion
of
the
calibration
cycle,
this
bit
is
automatically reset.
It is recommended that a calibration be executed
following system powerup. Upon release of the chip
reset, the Si3210 will be in the open state. The
calibration can be initiated after powering up the dc-dc
converter and allowing it to settle for time (tsettle).
Additional calibrations may be performed, but only one
calibration should be necessary as long as the system
remains powered up.
During calibration, VBAT, VTIP, and VRING voltages are
controlled by the calibration engine to provide the
correct external voltage conditions for the algorithm.
Calibration should be performed in the on-hook state.
RING or TIP must not be connected to ground during
the calibration.
When using the Si3201, automatic calibration routines
for RING gain mismatch and TIP gain mismatch should
not be performed. Instead of running these two
calibrations automatically, follow the instructions for
manual calibration in “AN35: Si321x User’s Quick
Reference Guide”.
2.2. Battery Voltage Generation and
Switching
The ProSLIC supports two modes of battery supply
operation. First, the Si3210 integrates a dc-dc converter
controller that dynamically regulates a single output
voltage. This mode eliminates the need to supply large
external battery voltages. Instead, it converts a single
positive input voltage into the real-time battery voltage
needed for any given state according to programmed
linefeed parameters. Second, the Si3211 supports
switching between high and low battery voltage
supplies, as would a traditional monolithic SLIC.
For single to low channel count applications, the Si3210
proves to be an economical choice, as the dc-dc
converter eliminates the need to design and build high-
voltage power supplies. For higher channel count
applications where centralized battery voltage supply is
economical or for modular legacy systems where
battery voltage is already available, the Si3211 is
recommended.
2.2.1. DC-DC Converter General Description
(Si3210/Si3210M Only)
The dc-dc converter dynamically generates the large
negative voltages required to operate the linefeed
interface. The Si3210 acts as the controller for a buck-
