LE58083ABGC

Telecom Overview

The LE58083ABGC is an Octal Low Voltage Subscriber Line Audio-Processing Circuit (Octal SLAC) manufactured by Microchip Technology. It integrates eight independent codec and filter channels within a single 121-pin BGA package. The device operates on low-voltage 3.3 V CMOS technology with 5 V tolerant digital inputs. It supports pin-programmable PCM/MPI or GCI interfaces, allowing flexible integration into telephone switch line cards. The architecture provides software-configurable transmission functions, including gain adjustment, equalization, and transhybrid balancing, ensuring compatibility with the VE580 series QLSLAC devices.

Telecom Feature Summary

• Integrates eight independent audio processing channels for codec and filtering functions
• Supports both standard PCM/microprocessor interface and General Circuit Interface (GCI)
• Features software-programmable digital filters for gain, equalization, and impedance scaling
• Compatible with Zarlink SLIC devices to provide complete BORSCHT functionality

Telecom Applications

• Codec function implementation on telephone switch line cards
• Subscriber line interface circuitry in telecommunications equipment
• Audio-processing circuits requiring high channel density and low power consumption

Telecom Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the specific ordering suffix matches the required package type and environmental compliance standards. Review the official datasheet revision history to ensure alignment with current design specifications and manufacturing updates before finalizing procurement orders.

Telecom Selection Notes

Select this component when designing subscriber line cards requiring multiple integrated audio channels. Ensure the system architecture supports either PCM/MPI or GCI interface modes as dictated by the host processor. Verify that the available master clock frequencies align with the required data rates for E1 or T1 multiplex operations.

Telecom Part Context

This device belongs to the Le58083 Octal SLAC family, designed to replace discrete codec solutions. It is based on the proven design of Zarlink’s reliable SLAC device families. The part number indicates the specific 121-pin BGA package variant compliant with RoHS directives.

Telecom Replacement Considerations

The LE58083ABGC is software and coefficient compatible with the VE580 series QLSLAC devices. Designers migrating from previous generations should verify register configurations and default filter coefficients to ensure seamless functional replacement without hardware modifications.
