2.2.5. DC-DC Converter Enhancements
Silicon
revisions
C
and
higher
support
two
enhancements to the dc-dc converter. The first is a
multi-threshold error control algorithm that enables the
dc-dc converter to adjust more quickly to voltage
changes. This option is enabled by setting DCSU = 1
(direct Register 108, bit 5). The second enhancement is
an audio band filter that removes audio band noise from
the dc-dc converter control loop. This option is enabled
by setting DCFIL = 1 (direct Register 108, bit 1).
2.2.6. DC-DC Converter During Ringing
When the ProSLIC enters the ringing state, it requires
voltages well above those used in the active mode. The
voltage to be generated and regulated by the dc-dc
converter during a ringing burst is set using the VBATH
register (direct Register 74). VBATH can be set between
0 and –94.5 V in 1.5 V steps. To avoid clipping the
ringing signal, VBATH must be set larger than the ringing
amplitude. At the end of each ringing burst, the dc-dc
converter adjusts back to active state regulation as
described above.
2.2.7. External Battery Switching (Si3211 Only)
The Si3211 supports switching between two battery
voltages. The circuit for external battery switching is
defined in Figure 14. Typically, a high-voltage battery
(e.g., –70 V) is used for on-hook and ringing states, and
a low-voltage battery (e.g., –24 V) is used for the off-
hook condition. The ProSLIC uses an external transistor
to switch between the two supplies.
When
the ProSLIC
changes
operating states,
it
automatically switches battery supplies if the automatic/
manual control bit, ABAT (direct Register 67, bit 3), is
set.
For example, the ProSLIC will switch from high battery
to low battery when it detects an off-hook event through
either a ring trip or loop closure event. If automatic
battery selection is disabled (ABAT = 0), the battery is
selected by the Battery Feed Select bit, BATSL (direct
Register 66, bit 1).
Silicon revisions C and higher support the option to add
a 60 ms debounce period to the battery switching circuit
when transitioning from high battery to low battery. This
option
is
enabled
by
setting
SWDB = 1
(direct
Register 108, bit 3). This debounce minimizes battery
transitions in the case of pulse dialing or other quick on-
hook to off-hook transitions.
2.3. Tone Generation
Two digital tone generators are provided in the ProSLIC.
They allow the generation of a wide variety of single- or
dual-tone frequency and amplitude combinations and
spare the user the effort of generating the required
POTS signaling tones on the PCM highway. DTMF, FSK
(caller ID), call progress, and other tones can all be
generated on-chip. The tones can be sent to either the
receive or transmit paths (see Figure 25 on page 50).
2.3.1. Tone Generator Architecture
A simplified diagram of the tone generator architecture
is shown in Figure 20. The oscillator, active/inactive
timers, interrupt block, and signal routing block are
connected to give the user flexibility in creating audio
signals. Control and status register bits are placed in the
figure to indicate their association with the tone
generator architecture. These registers are described in
more detail in Table 29.
