3 REN Ringing SLIC For ISDN Modem/TA  
and WLL  
Features  
• Thru-SLIC Open Circuit Ringing Voltage up to  
77V /54V , 3 REN Capability at 44V  
he HC5517 is a ringing SLIC designed to accommodate a wide  
variety of local loop applications. The various applications  
include, basic POTS lines with answering machines and fax  
capabilities, ISDN networks, wireless local loop, and hybrid  
fiber coax (HFC) terminals. The HC5517 provides a high  
degree of flexibility with open circuit tip to ring DC voltages, user  
defined ringing waveforms (sinusoidal to square wave), ring trip  
detection thresholds and loop current limits that can be tailored  
for many applications. Additional features of the HC5517 are  
complex impedance matching, pulse metering and transhybrid  
balance. The HC5517 is designed for use in systems where a  
separate ring generator is not economically feasible.  
PEAK RMS RMS  
• Sinusoidal Ringing Capability  
• DI Process Provides Substrate Latch Up Immunity when  
Driving Inductive Ringers  
• Adjustable On-Hook Voltage for Fax and Answering  
Machine Compatibility  
• Resistive and Complex Impedance Matching  
• Programmable Loop Current Limit  
• Switch Hook and Adjustable Ring Trip Detection  
• Pulse Metering Capability  
The device is manufactured in a high voltage Dielectric Isolation  
(DI) process with an operating voltage range from -16V, for off-  
hook operation and -80V for ring signal injection. The DI  
process provides substrate latch up immunity, resulting in a  
robust system design. Together with a secondary protection  
diode bridge and “feed” resistors, the device will withstand  
1000V lightning induced surges, in a plastic package.  
• Single Low Voltage Positive Supply (+5V)  
Applications  
• Solid State Line Interface Circuit for Wireless Local Loop,  
Hybrid Fiber Coax, Set Top Box, Voice/Data Modems  
A thermal shutdown with an alarm output and line fault  
protection are also included for operation in harsh  
environments.
