HC5520

CO/PABX Polarity Reversal

Subscriber Line Interface Circuit

April 1997

Features

Description

• Normal and Reversed DC Feed

The HC5520 is a Monolithic Subscriber Line Interface Circuit

(SLIC) for Analog Subscriber Line cards in Central Ofﬁce

and PABX switches.

• Current Limited Loop Feed

• Ringing, Test-In, and Test-Out Relay Drivers

• Thermal Shutdown Protection with Alert Signal

• On-Hook Transmission

The HC5520 provides a comprehensive set of features for

these applications including loop reversal, zero crossing

ringing relay operation, long loop drive and a mutually inde-

pendent setting of the receive and transmit gains, and the

two wire impedance synthesis. Advanced power manage-

ment features combined with a small 44 lead MQFP pack-

age allow signiﬁcant board space to be freed up for

additional line circuits.

• Selectable Transmit and Receive Gain Setting

• Selectable 2-Wire Impedance Matching

• Zero Crossing Ring Trip Detection and Ring Relay

Release

The HC5520 is fabricated in a Harris state-of-the-art Bonded

Wafer High Voltage process, providing freedom from tradi-

tional JI latch-up phenomena without the use of additional

power supply ﬁltering components or substrate tie connec-

tions. The very low parasitics and leakages associated with

this process provide an exceptionally ﬂat performance over

frequency and temperature.

• Parallel Digital Control and Status Monitoring

• Protection Resistors Inside Feedback Loop Allows the

Use of PTC Devices Without Impact on Longitudinal

Balance

• Thermal Management Features
