PBL 386 30/2  
Subscriber Line  
Interface Circuit  
Description  
Key Features  
The PBL 386 30/2 Subscriber Line Interface Circuit (SLIC) is a 90 V bipolar integrated  
circuit for use in Digital Loop Carrier, FITL and other telecommunications equipment.  
The PBL 386 30/2 has been optimized for low total line interface cost and a high  
degree of flexibility in different applications.  
The PBL 386 30/2 emulates resistive loop feed, programmable between 2x50 Ω  
and 2x900 Ω, with short loop current limiting adjustable to max 45 mA. In the current  
limited region the loop feed is nearly constant current with a slight slope  
corresponding to 2x30kΩ.  
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 and ring trip detection functions.  
The PBL 386 30/2 is compatible with loop start signaling.  
• 24-pin SSOP package  
• High and low battery supply with  
automatic switching  
• 65 mW on-hook power dissipation in  
active state  
• On-hook transmission  
• Long loop battery feed tracks Vbat for  
maximum line voltage  
• Only +5 V feed in addition to battery  
• Selectable transmit gain (1x or 0.5x)  
• No power-up sequence  
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  
two-wire impendance, 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 the DLC requirements.  
• Programmable signal headroom  
• 43V open loop voltage @ -48V battery  
feed  
• Constant loop voltage for line leakage  
<5 mA (RLeak ~ >10 kΩ @ -48V)  
The PBL 386 30/2 package options are 24-pin SSOP, 24-pin SOIC and  
28-pin PLCC.  
• Full longitudinal current capability  
during on-hook state  
• Analog over temperature protection  
permits transmission while the  
protection circuit is active  
• Integrated Ring Relay Driver
