MT9044AP1

Telecom Overview

The MT9044AP1 is a telecommunications interface integrated circuit manufactured by Microchip Technology, classified as a digital phase-locked loop (PLL). It operates within a supply voltage range of 4.5V to 5.5V and draws a supply current of 90mA. The device is housed in a 44-pin PLCC package with dimensions of 16.59x16.59 mm, designed for surface-mount installation. It supports an operating temperature range from -40°C to +85°C. The component contains one circuit and is RoHS3 compliant with an EAR99 classification. Moisture sensitivity level is rated at 1 (unlimited).

Telecom Feature Summary

• Integrates digital phase-locked loop functionality for telecommunications signal synchronization.
• Designed for T1/E1 network interface applications requiring precise timing recovery.
• Supports standard surface-mount assembly processes with a 44-PLCC form factor.

Telecom Applications

• T1/E1 digital telecommunication line interfaces
• Network synchronization equipment
• Telecom base station timing circuits

Telecom Procurement Notes

Verify component authenticity through authorized Microchip distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS3 compliance and moisture sensitivity handling requirements during storage and reflow soldering. Check for available replacement parts such as the ZL30102QDG1 if new production units are unavailable. Ensure packaging integrity matches specified reel quantities for automated assembly lines.

Telecom Selection Notes

Select this component when designing legacy T1/E1 telecom systems requiring a dedicated digital PLL in a 44-pin PLCC package. Verify that the 4.5V to 5.5V supply voltage aligns with the system power architecture. Consider the -40°C to +85°C industrial temperature range against environmental conditions. Evaluate pin compatibility and functional equivalence with newer replacements like the ZL30102QDG1 if upgrading designs.

Telecom Part Context

The MT9044AP1 belongs to Microchip's family of telecommunications interface ICs, specifically focusing on timing and synchronization solutions. It was previously distributed under Microsemi branding before corporate integration. The part is designated as obsolete with an End-of-Life date of May 27, 2016, limiting its availability to existing stock or alternative components.

Telecom Replacement Considerations

The ZL30102QDG1 is listed as a similar replacement by Microchip Technology. Verify pinout compatibility and register configuration differences before substitution in existing designs.
