1042M2-DT

Overview

The Agere Systems 1042M2-DT is a SONET/SDH compatible STS-13 byte processor housed in a space-saving, self-contained 20-pin DIP package. It utilizes a field-proven, reliable InGaAsP MOW laser and requires a single 5 V power supply. The component includes a parallel microprocessor interface that allows the user to define the architecture, initiate loopbacks, and monitor alarms.

Feature Summary

• SONET/SDH compatibility for telecommunications applications
• Integrated parallel microprocessor interface for architecture definition, loopback initiation, and alarm monitoring
• Utilizes field-proven InGaAsP MOW laser technology
• Operates on a single 5 V power supply

Applications

• SONET/SDH network equipment
• Telecommunications signal processing systems
• STS-1 byte processing applications

Procurement Notes

Verify the manufacturer designation as Agere Systems or its successor entities, such as Lantiq or Intel, due to corporate acquisitions. Confirm the specific suffix '-DT' corresponds to the intended temperature range and packaging variant. Ensure compliance with RoHS requirements if applicable to the specific production batch, noting that historical documentation may indicate varying standards. Cross-reference the part number with official distributor archives to confirm current availability status and moisture sensitivity level classification.

Selection Notes

Select this component for applications requiring STS-13 byte processing within SONET/SDH frameworks. The choice is driven by the need for a self-contained solution with a parallel microprocessor interface for system control. Consider the 20-pin DIP package for prototyping or legacy board designs. Evaluate the single 5 V supply requirement against available power rails. Verify the InGaAsP MOW laser suitability for the specific optical transmission parameters required by the design.

Part Context

The 1042M2-DT belongs to the 1042M2 series of programmable timers and oscillators produced by Agere Systems. This series is categorized under SONET/SDH compatible processors. The device represents a specialized integrated circuit designed for high-reliability telecommunications environments, leveraging established laser technology for signal integrity.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Due to the proprietary nature of the STS-13 byte processor and specific laser integration, direct pin-to-pin replacements from other manufacturers are not documented. Consult official Agere Systems or successor entity catalogs for potential obsolescence management strategies.
