DS1087LU-4CL/T&R

Overview

The DS1087LU-4CL/T&R is a programmable clock generator from the EconOscillator series by Analog Devices/Maxim Integrated. It operates on a single 3.3V supply with a voltage range of 2.7V to 3.6V and consumes 15mA of current. The device provides one output with a maximum frequency of 66.6 MHz, derived from an input frequency up to 400 kHz. Packaged in an 8-uSOP (uSOP-8) format for surface mount installation, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated spread-spectrum capability for EMI reduction
• Single 3.3V power supply operation
• Compact 8-pin uSOP surface-mount package

Applications

• General-purpose clock generation for digital systems
• EMI mitigation in consumer electronics
• Clock distribution for microcontrollers

Procurement Notes

Verify the specific suffix 'T&R' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors, as environmental certifications can vary by production batch. Ensure the operating voltage requirements align with the target system design before procurement.

Selection Notes

Select this component for applications requiring a low-pin-count, single-output clock source with spread-spectrum features. Verify that the required output frequency does not exceed 66.6 MHz and that the input clock signal stays within the 400 kHz limit. Consider the industrial temperature range (-40°C to +85°C) if the environment exceeds standard commercial limits.

Part Context

This part belongs to the DS1087L family of silicon oscillators. It serves as a drop-in replacement for traditional crystal oscillator assemblies, offering programmability and reduced bill-of-materials complexity. The EconOscillator line integrates the oscillator circuitry directly onto the silicon die.

Replacement Considerations

Compatible variants include DS1087LU-4CL+ and DS1087LU-4CL-W. Note that suffixes may indicate differences in packaging (tube vs. reel) or lead-free status. Cross-reference with DS1086L series devices only if pinout and electrical specifications are verified to be identical.
