LE58QL061BVC

Telecom Overview

The LE58QL061BVC is a Quad Low Voltage Subscriber Line Audio-Processing Circuit (QLSLAC) manufactured by Microchip Technology. It integrates four independent codec/filter channels for telecommunications applications. The device operates on low-power 3.3 V CMOS technology with 5 V tolerant digital inputs and is housed in a 44-pin TQFP package. It supports pin-programmable PCM/MPI or GCI interfaces, allowing flexible integration into line card designs.

Telecom Feature Summary

• Integrates four independent signal processing channels performing codec and filter functions
• Supports software-configurable SLIC device input impedance and transhybrid balance
• Provides programmable Digital I/O pins with built-in debounce filters
• Enables mixed state analog and digital impedance scaling

Telecom Applications

• Codec function implementation on telephone switch line cards

Telecom Procurement Notes

Verify the component origin as Zarlink Semiconductor Inc., now part of Microchip Technology. Confirm the specific ordering suffix 'BVC' corresponds to the 44-pin TQFP tray packaging configuration. Ensure compliance with RoHS Directive 2002/95/EC requirements before procurement.

Telecom Selection Notes

Select this component when designing subscriber line interface circuits requiring four-channel audio processing. It serves as a direct software and coefficient compatible replacement for the Le79Q061/063 QSLAC devices. Verify that the system architecture supports the required PCM or GCI interface modes.

Telecom Part Context

This device belongs to the Ve580 Series of Quad Low Voltage Subscriber Line Audio-Processing Circuits. It utilizes advanced submicron CMOS technology to provide high performance and low power consumption, maximizing line card density while minimizing cost in telecommunications equipment designs.

Telecom Replacement Considerations

The LE58QL061BVC is software and coefficient compatible with the Le79Q061/063 QSLAC devices. Design conversion guides are available to facilitate migration from legacy QSLAC architectures to this QLSLAC platform.
