Description
The ringing FlexiSLIC PBL 38773/1 Subscriber Line Interface Circuit (SLIC) is a 90 V
bipolar integrated circuit for use in short loop applications. The PBL 38773/1 SLIC has
been optimized for low power consumption, low total line interface cost and for a high
degree of flexibility in various applications.
The PBL 38773/1 SLIC supplies a balanced, sinewave, square or trapezoidal ringing
signal of up to 81 VPeak (85 V DC supply) to the subscriber line across a load of up to
5 REN. The PBL 38773/1 supplies programmable constant current to the subscriber
loop, sourced from the talk battery. The On-Hook line voltage of 43 V to 56 V is derived
from the battery. All battery switching is internal to the device and is automatic. To further
reduce power consumption the automatic gain control for the ring signal (AGC-R) keeps
the level always adjusted to the maximum, that can be sourced from the available
battery.
The SLIC incorporates loop current, ground key and ring-trip detection functions. The
PBL 38773/1 is compatible with loop start and ground start signalling. Two- to four-wire
and four- to two-wire voice frequency (vf) signal conversion is accomplished by the SLIC
in conjunction with a standard codec. The line terminating impedance and balance
impedance is programmable and may be complex or real for worldwide compliance.
Longitudinal balance specifications and other device characteristics are in compliance
with Telcordia (Bellcore) and ITU-T requirements.
Tip and ring voltages are UL-1950 compliant; i.e. no two-wire line voltage exceeds 56 V.
The PBL 38773/1 SLIC is packaged in a surface mount 28-pin SOIC or 32-pin MLP
(32-pin VQFN) package.
