A parallel interface allow to control the operation
of STLC3080through a control bus:
- D0 D1 D2 latchedinput bits definingthe Slic
operationmode
- R0 R1 latched input bits (activeHigh) drive the
test relays.
- DET and GDK/AL , tri-stateoutputs, signal the
statusof the loop:On/Off-HookandGround-Key.
PinGDK/AL goeslow alsowhenthe device
thermalprotectionis activatedor a linefault(Tip to
Ring,Tip and/orRing to Groundor VBAT)is
detected(flowing current
≥
7.5mA).
-CSIN: chipselect for input bits, active Low,
strobesthe data presenton the control bus into
theinternal latch.
- CSOUT: chipselectforoutputbits; activeLow,
whenhigh DET and GDK/AL goes tri-state.
D0 D1 D2 R0 R1 CSIN and CSOUT inputs are
provided with a 15
μ
A pull-down current to prevent
uncontrolled conditions in case the control bus
goes floating.
According to the above table, 8 operating modes
can be set:
1) Power-Down.
2) Stand-By.
3) ActiveN.P.
4) ActiveR.P.
5) Ringing(with SLIC Active N.P.).
6) Ringing(with SLIC Active R.P.).
7) Groundstart.
8) HighImpedanceFeeding.
Power-Down
It’s an idle state characterised by a very low
power consumption; any functionalityis disabled;
only
relays Rel0 and Rel1 can be
proper settingof bitsR0 and R1.
It can be set during out of service periods just to
driven by
reducethe power consumption.
It is worth noticing that two other conditions can
set the Slic in idle state but with some differences
as reportedin the table:

Mode selected in On-Hook condition when high
immunity to common mode currents is neededfor
the DET bit.
To reduce the current consumption, AC feedback
loop is disabled and only DET and GDK/AL de-
tectors are active.
DC current is limited at 16mA (not programma-
ble); feedingcharacteristicshown in fig.a.
The voltagedrop in on-hook conditionis 7.8V.

Active
Mode selected to allow voice signal transmission.
When in ACTIVE mode the voltage drop in on-
hook condition is 7.8V in order to allow proper on-
hook transmission (Fig. b).
