DS1086LU-12F

Overview

The DS1086LU-12F is a 3.3V Spread-Spectrum EconOscillator clock generator manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.7 V to 3.6 V and features an output frequency of 12 MHz. The device utilizes an 8-pin UMAX package for surface-mount installation. It supports a maximum duty cycle of 60% and functions within a temperature range of -20°C to +85°C. This component is classified under Clock Generators & Support Products.

Feature Summary

• Generates spread-spectrum clock signals to reduce electromagnetic interference
• Operates as a low-cost fixed-frequency oscillator solution
• Designed for automotive temperature range applications

Applications

• Reducing EMI in high-speed digital circuits
• Clock generation for switched-mode power supplies
• Automotive electronic system timing

Procurement Notes

Verify the specific suffix (e.g., +T&R) against official documentation, as it determines packaging type such as Reel or Cut Tape. Confirm current availability status, as this product line may be subject to limited supply or discontinuation notices from the manufacturer. Ensure RoHS compliance details match the specific revision required for your assembly process.

Selection Notes

Select this component when a fixed 12 MHz spread-spectrum clock is required for EMI reduction. It is suitable for designs needing a single output with minimal external components. Consider the 8-pin UMAX package constraints for PCB layout. Verify that the 3.3V operating voltage aligns with the target system's power rails.

Part Context

This part belongs to the DS1086LU series of EconOscillators, which are designed to provide cost-effective clock solutions. The series includes various frequency options and packaging variants. These devices integrate the oscillator and control circuitry into a single compact package, simplifying design implementation compared to discrete crystal-based solutions.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Check for direct pin-compatible alternatives within the same DS1086LU family if frequency variations are acceptable.
