Overview

Description
The PBL 38620/2 Subscriber Line Interface Circuit (SLIC) is a 90 V bipolar integrated
circuit for use in PBX, Terminal adapters and other telecommunications equipment. The
PBL 38620/2 SLIC has been optimized for low total line interface cost and for a high
degree of flexibility in different applications.
The PBL 38620/2 SLIC has constant current feed, programmable to maximum 30 mA.
A second lower battery voltage may be connected to the device to reduce short loop
power dissipation. The SLIC automatically switches between the two battery supply
voltages without need for external components or external control.
The SLIC incorporates loop current, ground key and ring-trip detection functions. The
PBL 38620/2 is compatible with loop start signalling.
Two- to four-wire and four- to two-wire voice frequency (VF) signal conversion is
accomplished by the SLIC in conjunction with either a conventional CODEC/filter or with
a programmable CODEC/filter, for example SiCoFi PEB 2466. The programmable two-
wire impedance, complex or real, is set by a simple external network.
Longitudinal voltages are suppressed by a feedback loop in the SLIC and the
longitudinal balance specifications meet Bellcore TR909 requirements.
The PBL 38620/2 SLIC package options are 24-pin SSOP, 24-pin PDSO or 28-pin
PLCC.
