FUNCTIONAL DESCRIPTION
DIGITAL INTERFACE
The different operating modes of the L3235N are
programmed through a digital interface based on
two input pins:
1)SBY input programs the stand-by or Ac-
tive/Ringing modes.
2)RNG input programs the ringing ON/OFF acti-
vation condition for the L3234.
The L3235N digital interface has four output pins :
1)OH provides the on hook/off hook or ring trip
informations (active low).
2)GDK provides the ground key on/off informa-
tion (active low).
3)PU must be connected to the enable input pin
of CODEC/FILTER devices like ETC 5054/57
and automatically activates this device when
in active mode off-hook is detected or when
ringing mode is selected.
4)CS output must be connected to the CS en-
able input of the solid state ringing injector
L3234.
In this way the L3234 will be enabled when ring-
ing mode is programmed and will be automat-
ically disabled when the ring trip condition will be
detected reducing the ringing signal disconnec-
tion time after ring trip.
The table 1 here below resumes the different op-
eration modes and the relative logic output sig-
nals.
The two current detection (hook and GND key)
have internal fixed threshold. Externally it is possi-
ble to program their time costant through two R-C
components connected respectively to pin 26
(RTF) and pin 27 (GKF).
