4.13. Two-Wire Impedance Synthesis
Two-wire impedance synthesis is performed on-chip to
optimally match the output impedance of the Si3232 to
the impedance of the subscriber loop, thus minimizing
the receive path signal reflected back onto the transmit
path. The Si3232 provides on-chip selectable analog
two-wire impedances to meet return loss requirements.
The subscriber loop varies with any series impedance
due to protection devices placed between the Si3200
outputs and the TIP/RING pair according to the
following equation:
Where:
ZT is the termination impedance presented
to the TIP/RING pair
RPROT is the series resistance caused by
protection devices
RA is the analog portion of the selected
impedance
Therefore, the user must also consider the value of
RPROT
when
programming
the
on-chip
analog
impedance.
The Si3232’s analog impedance synthesis scheme is
sufficient for many short loop applications. If a unique
complex ac impedance is required, the Si3232’s
impedance scheme must be augmented or replaced by
a DSP-based impedance generator. To turn off the
analog impedance coefficients (RS, ZP, and ZZ), set the
ZSDIS bit of the ZZ register to 0.

4.13.1. Transhybrid Balance Filter
The Si3232 is intended to be used with DSP-based
codecs that provide the transhybrid balance function.
No transhybrid capability exists in the Si3232.
4.13.2. Pulse Metering Generation
The Si3232 offers an internal tone generator suitable for
generating tones above the audio frequency band. This
oscillator is provided for the generation of billing tones
which are typically 12 kHz or 16 kHz. The equations for
calculating the pulse metering coefficients are as
follows:
Coeff = cos (2
f/64000 Hz)
PMFREQ = coeff (214 – 1)
