LE58QL02FJCT

Telecom Overview

The LE58QL02FJCT is a Quad Low Voltage Subscriber Line Audio-Processing Circuit (QLSLAC) manufactured by Microchip Technology. It integrates four independent codec and filter channels for telephone switch line cards. The device operates on low-power 3.3 V CMOS technology with 5-V tolerant digital inputs. It supports A-law, µ-law, or linear coding and features software-programmable parameters including input impedance, transhybrid balance, gains, and equalization. The component utilizes a standard microprocessor interface and offers single or dual PCM port configurations.

Telecom Feature Summary

• Performs codec and filter functions for four independent subscriber lines
• Software programmable for gain, impedance, and frequency response
• Compatible with Le79Q02/021/031 QSLAC devices
• Supports standard microprocessor interface and PCM highway signaling

Telecom Applications

• Codec function on telephone switch line cards

Telecom Procurement Notes

Verify the specific ordering suffix to confirm package type and packing method. The 'F' indicates a 44-pin PLCC package, while 'T' denotes tape and reel delivery. Confirm RoHS compliance status as required by project specifications. Ensure compatibility with existing system voltage levels and clocking requirements before procurement.

Telecom Selection Notes

Select this component when designing programmable line cards requiring integrated audio processing. It serves as a direct replacement for legacy SLAC devices due to coefficient compatibility. Consider the 44-pin PLCC package availability and verify if dual PCM highway support is necessary for the specific application architecture.

Telecom Part Context

This device belongs to the Le58QL02/021/031 family of QLSLAC circuits. It is based on Legerity’s reliable SLAC design families. The component provides a cost-effective solution for maximizing line card density through advanced submicron CMOS technology and low power consumption characteristics.

Telecom Replacement Considerations

The LE58QL02FJCT is software and coefficient compatible with the Le79Q02/021/031 QSLAC devices. Designers converting from older architectures should utilize the provided QSLAC to QLSLAC conversion guides to ensure functional equivalence.
