LE58QL063HVCT

Telecom Overview

The LE58QL063HVCT is a Quad Low Voltage Subscriber Line Audio-Processing Circuit (QLSLAC) manufactured by Microchip Technology. It integrates four independent codec/filter channels for telecommunications line cards, supporting A-law, µ-law, or linear coding. The device operates on low-power 3.3 V CMOS technology with 5 V tolerant digital inputs and features pin-programmable PCM/MPI or GCI interfaces. It supports master clocks of 1.536, 1.544, 2.048, 3.072, 3.088, 4.096, 6.144, 6.176, or 8.192 MHz in PCM mode, and 2.048 MHz or 4.096 MHz in GCI mode. The component is housed in a 64-pin LQFP package.

Telecom Feature Summary

• Integrates four independent signal processing channels performing codec and two-to-four-wire conversion functions.
• Supports software and coefficient compatibility with legacy QSLAC devices for simplified design migration.
• Features programmable digital filters for transhybrid balancing, impedance matching, and equalization.
• Provides flexible interface options including standard PCM/microprocessor interface and General Circuit Interface.

Telecom Applications

• Codec function implementation on telephone switch line cards
• Subscriber line interface circuitry in telecommunications equipment
• BORSCHT function solutions when paired with SLIC devices

Telecom Procurement Notes

Verify the specific suffix 'HVC' to confirm the 64-pin LQFP package configuration. Ensure the ordering part number includes the 'T' suffix if tape and reel packing is required instead of trays. Confirm that the source document identifies Zarlink Semiconductor as the original manufacturer before acquisition by Microchip Technology.

Telecom Selection Notes

Select this model over the LE58QL061 variant when a 64-pin LQFP package is preferred over the 44-pin TQFP option. Verify that the system requires four independent audio channels with mixed state impedance scaling. Ensure the application utilizes either PCM/MPI or GCI modes compatible with the device's pin-programmable interface selection.

Telecom Part Context

This component belongs to the Le58QL061/063 QLSLAC series within the Ve580 product family. It serves as a high-performance, very-programmable solution for integrating analog line card functions into digital systems. The device is based on advanced submicron CMOS technology designed to maximize line card density while minimizing power consumption.

Telecom Replacement Considerations

The LE58QL061BVC is a related device offering identical functionality but packaged in a 44-pin TQFP format. Designers migrating from older QSLAC families should consult the official design conversion guide to ensure coefficient compatibility and proper register mapping during the transition process.
