CS61584A-IQ5Z

Telecom Overview

The CS61584A-IQ5Z is a dual T1/E1 line interface integrated circuit manufactured by Cirrus Logic Inc. It operates on a 5.0V supply and is housed in a 64-pin TQFP package, supporting an ambient operating temperature range of -40°C to +85°C. The device integrates two independent line interfaces featuring matched impedance transmit drivers, crystal-less jitter attenuation, and customizable pulse shaping. It supports serial and parallel host mode operations alongside hardware mode configurations.

Telecom Feature Summary

• Dual T1/E1 Line Interface
• Crystal-less Jitter Attenuator
• Matched Impedance Transmit Drivers
• JTAG Boundary Scan Support

Telecom Applications

• T1/E1 Line Interface Cards
• Asynchronous Multiplexer Applications
• Synchronous Application Systems

Telecom Procurement Notes

Verify the specific suffix IQ5Z against official documentation to confirm the 5.0V supply voltage requirement and 64-pin TQFP package type. Ensure compatibility with the specified -40°C to +85°C operating temperature range for your target environment before procurement.

Telecom Selection Notes

Select this component for high-density applications requiring low power consumption and flexible microprocessor control via serial or parallel interfaces. Consider the crystal-less jitter attenuation feature if meeting European CTR 12 and ETSI specifications is required without external oscillators.

Telecom Part Context

This part belongs to the CS61584A family of dual line interfaces designed for T1/E1 applications. Other variants include the CS61584A-IQ3 (3.3V, 64-pin TQFP) and CS61584A-IL5 (5.0V, 68-pin PLCC), offering different voltage levels and package options within the same functional scope.

Telecom Replacement Considerations

Direct substitutes are not explicitly listed in the provided datasheet. Evaluate the CS61584A-IQ3 for 3.3V systems or the CS61584A-IL5 for PLCC packaging requirements, ensuring pinout and voltage compatibility.
