PBL 386 11/2  
Subscriber Line  
Interface Circuit  
Description  
Key Features  
• Selectable overhead voltage principle  
– All adaptive: The overhead voltage  
follows 0.6 VPeak < signals < 5 VPeak  
– Semi adaptive: The overhead  
The PBL 386 11/2 Subscriber Line Interface Circuit (SLIC) is a 90 V bipolar inte-  
grated circuit for use in DAML, FITL and other telecommunications equipment. The  
PBL 386 11/2 has been optimized for low total line interface cost and a high degree  
of flexibility in different applications.  
The PBL 386 11/2 emulates a transformer equivalent dc-feed, programmable  
between 2x25 Ω and 2x900 Ω, with short loop current limiting adjustable to max  
65 mA.  
.
voltage follows 2.5 VPeak < signals <  
5 VPeak  
.
• Metering 1.6 Vrms  
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 386 11/2 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, e.g. SLAC, SiCoFi, Combo II. The programmable  
line terminating impedance could be complex or real to fit every market.  
Longitudinal line voltages are suppressed by a feedback loop in the SLIC and the  
longitudinal balance specifications meet Bellcore TR909 requirements.  
The PBL 386 11/2 package are 28-pin PLCC and 28 pin SSOP.  
• High and low battery with automatic  
switching  
• Battery supply as low as -10V  
• Only +5V in addition to GND  
and battery (VEE optional)  
• 35 mW on-hook power dissipation in  
active state  
• Long loop battery feed tracks VBat for  
maximum line voltage  
• 44V open loop voltage @ -48V battery  
feed  
• Constant loop voltage for line  
leakage <5 mA  
• On-hook transmission  
• Full longitudinal current capability
