HC55185GIM

Telecom Overview

The HC55185GIM is a Ringing Subscriber Line Interface Circuit (RSLIC) from the RSLIC-VoIP family, designed for analog Plain Old Telephone Service (POTS). It operates up to 100V, supporting subscriber loop lengths of 500Ω or more. The device features low power consumption and supports sinusoidal or trapezoidal ringing waveforms. It includes robust auto-detection for on-hook/off-hook states and integrated test access for loopback and line measurement. The voltage feed amplifier uses low fixed loop gains for high analog performance and noise immunity.

Telecom Feature Summary

• Supports high ringing voltage up to 100V for extended subscriber loops
• Enables flexible waveform generation including sinusoidal and trapezoidal options
• Integrates automatic detection mechanisms for subscriber line status changes
• Provides internal test access features for loopback and line measurements

Telecom Applications

• Analog POTS in short and medium loop length applications
• Wireless and wireline remote subscriber units
• VoIP systems requiring high ringing voltage with low power consumption

Telecom Procurement Notes

Verify the manufacturer designation, as the component is associated with Intersil, Renesas, and Rochester Electronics. Confirm the package type matches PQCC28 or LCC-28 specifications. Ensure the specific voltage grade and longitudinal balance requirements align with the design needs before procurement.

Telecom Selection Notes

Select this component when designing systems that require operation up to 100V for ring signaling. Consider the low power consumption characteristics for battery-operated or energy-efficient remote units. Evaluate the need for integrated test access features if loopback testing is required during production or maintenance.
