DS1086LU-CCJ

Overview

The DS1086LU-CCJ is a 3.3V spread-spectrum EconOscillator manufactured by Analog Devices (Maxim Integrated). It functions as a clock generator designed to reduce electromagnetic interference (EMI) in digital systems through frequency dithering. The device operates within a supply voltage range of 2.7V to 3.6V and supports output frequencies up to 33MHz. It utilizes a silicon-based oscillator architecture, eliminating the need for external crystals or resonators. The component is housed in an 8-pin uMAX package, suitable for surface-mount applications in space-constrained designs.

Feature Summary

• Integrated spread-spectrum clock generation to minimize radiated emissions
• No external crystal or resonator required for operation
• Supply voltage range of 2.7V to 3.6V
• Available in compact 8-pin uMAX surface-mount package

Applications

• Microcontroller clock sources requiring EMI reduction
• Consumer electronics with strict EMC compliance needs
• Digital signal processing systems utilizing low-voltage power supplies

Procurement Notes

Verify the specific suffix 'CCJ' against official manufacturer documentation to confirm pinout compatibility and temperature grade. Check current lifecycle status, as older Maxim Integrated clock generators may be subject to discontinuation or limited availability. Ensure the selected variant matches the required output frequency and load capacitance specifications for the target application.

Selection Notes

Select this component when a fixed-frequency, low-cost clock source with built-in EMI suppression is required. Compare the available output frequencies against the system's timing requirements. Consider the thermal performance within the 8-pin uMAX package if operating near the upper limits of the specified temperature range. Verify that the 3.3V supply rail is stable within the 2.7V to 3.6V operational window.

Part Context

The DS1086L series belongs to Maxim Integrated's EconOscillator family, which provides crystal-less clock solutions. These devices are engineered to replace traditional quartz oscillators in cost-sensitive and space-limited applications. The spread-spectrum feature specifically targets the reduction of peak harmonic amplitudes in digital circuits.

Replacement Considerations

Consult the official datasheet for direct pin-to-pin replacements within the DS1086L family. Alternative silicon oscillators from other manufacturers may require circuit redesign due to differences in drive strength, output logic levels, or spread-spectrum modulation parameters.
