Description  
The ringing FlexiSLIC™ PBL 387 82/1 Subscriber Line  
Interface Circuit (SLIC) is a 90 V bipolar integrated  
circuit for use in short loop cable modem applications.  
The PBL 387 82/1 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 387 82/1 SLIC supplies a balanced, sinewave  
or trapezoidal ringing signal of up to 81 VPeak (85 V  
DC supply) to the subscriber line across a load of up  
to 5REN. The PBL 387 82/1 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 and ring trip  
detection functions. The PBL 387 82/1 is compatible  
with loop start signalling. Two- to four-wire and  
four- to two-wire voice frequency (vf) signal con-  
version is accomplished by the SLIC in conjunction  
with Broadcom cable modem circuit BCM3352. The  
line terminating impedance and balance impedance  
is programmable and may be complex or real for  
worldwide compliance. The PBL 387 82/1 includes a  
differential codec interface.  
Longitudinal balance specifications and other device  
characteristics are in compliance with ITU-T require-  
ments.  
Tip and ring voltages are UL-1950 compliant; i.e. no  
twowire line voltage exceeds 56 V. The PBL 387 82/1  
SLIC is packaged in a surface mount 44-pin QSOP  
package.
