CS61584A-IL3

Telecom Overview

The CS61584A-IL3 is a dual T1/E1 line interface unit manufactured by Cirrus Logic Inc. It operates at a data rate of 2.048 Mb/s and supports two channels within a single integrated circuit. The component is housed in a compact 68-pin PLCC (J-Lead) package, measuring 24.23x24.23 mm, designed for surface-mount applications. It functions as a Subscriber Line Interface Concept (SLIC) device with parallel interface capabilities. The unit requires a 3.3V supply voltage and is rated for an operating temperature range from -40°C to 85°C.

Telecom Feature Summary

• Dual channel architecture supporting simultaneous T1 and E1 line interface operations
• Compact 68-pin PLCC package optimized for high-density board layouts
• Low power consumption design suitable for high-volume telecommunications cards

Telecom Applications

• T1 telecommunication line interface units
• E1 telecommunication line interface units
• High-density telecommunications equipment cards

Telecom Procurement Notes

Verify the specific suffix IL3 confirms the 68-PLCC package variant when sourcing. Ensure compatibility with 3.3V logic levels and check that the operating temperature range meets the environmental requirements of the target deployment. Confirm the manufacturer is Cirrus Logic Inc. to avoid counterfeit components.

Telecom Selection Notes

Select this component for designs requiring dual T1/E1 connectivity in space-constrained environments. The PLCC package offers a balance between pin count and footprint size. Consider the -40°C to 85°C rating for industrial or outdoor telecom deployments where standard commercial ranges are insufficient.

Telecom Part Context

This part belongs to the Cirrus Logic CS61584A series, which provides dual line interfaces for T1/E1 applications. The series is engineered for high-volume production cards where low power usage and high integration density are critical requirements for modern telecommunications infrastructure.
