DS1087LU-23C/W

Overview

The DS1087LU-23C/W is a discontinued clock generator from the EconOscillator series by Analog Devices/Maxim Integrated. It operates on a single 3.3V supply and features spread-spectrum capabilities to reduce electromagnetic interference (EMI). The device generates a maximum frequency of 16.6MHz with one output circuit. It is housed in an 8-uMAX/uSOP surface-mount package and supports an industrial operating temperature range of -40°C to +85°C.

Feature Summary

• Integrated spread-spectrum clock generation for EMI reduction
• Single 3.3V power supply operation
• Maximum output frequency of 16.6MHz
• Compact 8-pin uMAX or uSOP surface-mount package

Applications

• General-purpose clock generation for digital systems
• Applications requiring low-cost, fixed-frequency clock sources
• Systems needing basic EMI mitigation through spread spectrum

Procurement Notes

This component is officially listed as obsolete or discontinued by the manufacturer. Availability is restricted to remaining stock from distributors. Verification of authenticity and storage history is critical due to the end-of-life status. No new production units are expected from Analog Devices/Maxim Integrated.

Selection Notes

Designers should verify if the fixed 16.6MHz output and 3.3V supply meet system requirements, as the device lacks programmability. Consider the 8-pin package constraints for PCB layout. Since the part is discontinued, evaluate alternative clock generators with similar specifications that are currently in active production to ensure long-term supply stability.

Part Context

The DS1087L series belongs to Maxim Integrated's EconOscillator family, designed to provide simple, cost-effective clock solutions without external crystals or resonators. The 'LU' suffix typically denotes specific packaging and temperature grade variations within this line. This model represents a legacy solution for basic timing needs before more advanced programmable alternatives became standard.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific obsolete model. Engineers must select a modern equivalent based on functional parameters such as output frequency, voltage, and package type. Cross-referencing with current Analog Devices clock generator portfolios is recommended.
