DESCRIPTION  
The Zarlink Le9502 Ringing Subscriber Line Interface Circuit  
(RSLIC) device from the VE950 series has enhanced and  
optimized features to directly address the requirements of  
FEATURES  
„ Integrated Dual-Channel Device  
— Built-in boost switching power supply tracks line voltage Voice over Broadband applications. Its goal is to reduce system  
minimizing power dissipation  
level costs, space, and power through higher levels of  
integration, and to reduce the total cost of ownership by offering  
better quality of service. The Le9502 RSLIC device provides a  
totally configurable solution to the BORSCHT functions for two  
lines. The resulting system is less complex, smaller, and  
denser, yet cost effective with minimal external components.  
The Le9502 RSLIC device requires only two power supplies:  
+3.3 VDC and nominally +12 VDC. The latter power supply can  
range from +8 VDC to +40 VDC, depending on the application.  
A single TTL-level clock source drives an external transistor  
which controls the ramp voltage that in turn feeds the switching  
regulators. Five programmable states are available: Active,  
Reverse Polarity, Ringing, Standby, and Disconnect. The DC  
feed, two-wire AC input impedance, hook-switch threshold, and  
ring trip threshold are programmable via external discrete  
components. Binary fault detection is provided upon  
application of fault conditions or thermal overload.  
— Only +3.3 V and +12 V (nominal) required  
— Wide range of input voltages (+8 V to +40 V) supported  
— Minimal external discrete components  
— 44-pin eTQFP package  
„ Ringing  
— 70 Vpk into 5REN  
— 90 Vpk capable  
— Sinusoidal or trapezoidal capability  
— DC offset support  
— Common differential interface for both channels  
„ World Wide programmability:  
— Two-wire AC impedance  
— Dual Current Limit  
— Loop closure and ring trip thresholds  
„ Five SLIC States, including:  
— Low power Standby state  
— Reverse Polarity
