The signal processing inside the STLC3040 is
both analog and digital merging the best available
analog and digital processing performances of the
BiCMOS technology.
The L3000N/STLC3040 kit is fully programmable
and needs only 5 ext. resistors (including the two
protection resistors) and 3 capacitors. These
components are always the same; all the parame-
ters related to different applications are software
programmed. Considering the DC characteristic,
by proper programming it is possible to select
several limiting currents (from 0 to 70mA with
1.1mA steps, different DC feeding resistance
(from 0 to 2 x 400
with 100 steps) and differ-
ent drop voltages (on-hook transmission, meter-
ing pulse injection).
Considering AC performances all possible 2-wire
impedances are software programmable, the
same for the two to four wire conversion, where
all the possible balance impedances can be soft-
ware programmed. Both Tx and Rx gain are pro-
grammable (12 dB range, 0.1dB step) with proper
frequency equalization that will guarantee a com-
plete flat response in the speech band.
Ringing signal is also generated on chip with pro-
grammable frequency and amplitude. For this
purpose the L3000N device in addition to the
negative battery (VB-) requires also a positive
one (VB+). VB- can vary between -70V to -24V
depending on the application. The VB+ is usually
selected in order to have a total battery voltage
|VB+|+|VB-| = 120V.
Ring injection and disconnection is always per-
formed in correspondance of zero crossing. In ad-
dition when ring trip is detected the ring signal is
automatically disconnected again at the first zero
crossing. The kit is also able to generate metering
pulse signals (12 or 16kHz) with programmable
amplitudes up to 5Vrms. Polarity reversal is sup-
ported.
Finally several testing features are provided by
the kit. This means that the kit is able both to test
itself and also the line parameters (leakage, ca-
pacitance ..) saving the testing relays and the
equipment needed to perform the test.
