Le79555  
Subscriber Line Interface Circuit  
VE580 Series  
APPLICATIONS  
DESCRIPTION  
The Le79555 device, part of the Zarlink VoiceEdge™ family  
VE580 series of devices, was designed for high-density POTS  
applications requiring a power saving, small footprint SLIC  
device. The new SLIC device fulfills today's requirements for  
POTS linecard markets requiring a balance of high-  
performance cost-effective silicon components. The Le79555  
device delivers economical linecard solutions by offering power  
and space savings to linecard designers. The on-chip  
switching regulator allows for power dissipation to be  
minimized for the entire system. Another benefit is that the  
device is offered in a reduced footprint package type, a 44-pin  
TQFP. This small footprint saves designers board space, thus  
increasing the density or number of lines on the board.  
„ Ideal for high-density, low-power linecard applications  
FEATURES  
„ Control states: Active, Reverse Polarity, Tip Open,  
Ringing, Standby, and Open Circuit  
„ Low Standby power  
„ –40 to –58 V battery operation  
„ On-hook transmission  
„ Two-wire impedance set by single external impedance  
„ Programmable constant-current feed  
„ Low Off-Hook Active Overhead Voltage  
„ Programmable loop-detect threshold  
„ Ground-start detector  
Zarlink offers a range of compatible SLAC™ devices  
providing a complete line circuit that can be optimized for  
varying requirements. The SLIC device is designed to operate  
with a range of SLAC devices from low cost, non-  
programmable to more advanced, highly programmable  
options viable for a range of applications.  
„ Programmable ring-trip detect threshold  
„ No –5 V supply required  
„ Three on-chip relay drivers and relay snubbers, one  
ringing and two general purpose  
„ Tip Open state for ground-start lines  
„ On-chip switching regulator for Low power dissipation  
„ Supports 30 mA for Active, Normal, and Reverse  
Polarity operation
