Preliminary Information  
February 2000  
PBL 386 15/1  
Subscriber Line  
Interface Circuit  
Description  
Applications  
• ISDN Network terminals  
• DAML  
• FITL  
• Shortloop applications  
The PBL 386 15/1 Subscriber Line Interface Circuit (SLIC) is a 90 V bipolar integrated  
circuit for use in ISDN Network Terminal Adapters, DAML, FITL and other short loop  
telecommunication equipment which often are remote powered, and by that, the  
available power is limited. The PBL 386 15/1 has been optimized for low total line  
interface cost, low power and requires a minimum of external components.  
The PBL 386 15/1 has constant current feed, programmable to max 30mA. The SLIC  
uses a first battery voltage for On-hook . A second battery voltage is used for  
Off-hook and must be connected, 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 loop current controls the switching  
between On-hook and Off-hook battery.  
Key Features  
• Small footprint with SSOP package  
• On-hook and Off-hook battery with  
automatic switching, controlled by  
loop current  
• On-hook battery current is limited  
to 6 mA  
• 37 mW on-hook power dissipation in  
active state  
• Metering 0.5 Vrms (0.7 Vpeak)  
• Adaptive Overhead Voltage  
The overhead voltage follows  
1Vpeak<signals<2.5Vpeak  
• Battery supply as low as -10V  
• Only +5V in addition to GND  
and battery (VEE optional)  
• Open loop voltage tracks On-hook  
battery  
The SLIC incorporates loop current, ground key and ring trip detection functions.  
The PBL 386 15/1 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, e.g. SLAC, SiCoFi, Combo II. The programmable line terminating  
impedance could be complex or real to fit every market. Longitudinal voltages are  
suppressed by a feedback loop in the SLIC and the longitudinal balance specifica-  
tions meet Bellcore TR909 requirements.  
The PBL 386 15/1 package is a very PCB space efficient 28-pin SSOP.
