The High Voltage Subscriber Line IC PEB 4065 is a
rugged and reliable interface between the telephone
line and the SLICOFI, a low voltage Subscriber Line
Interface and Codec Filter IC. It is fabricated in a Smart
Power Technology offering a breakthrough voltage of
at least 170 V.
The PEB 4065 provides battery feeding between
– 24 V and – 80 V and internal ringing injection with a
differential ring voltage up to 85 Vrms. In order to
achieve these high amplitudes an auxiliary positive battery voltage is used during
ringing. This voltage can also be applied in order to drive very long telephone lines.
The SLIC is designed for a voltage feeding – current sensing line interface concept and
provides sensing of transversal and longitudinal current on both wires.
A power-down mode offers reduced power consumption at full functionality; in the power
denial mode the device is switched off turning the line outputs to a high impedance state.
