DS1087LU-40K

Overview

The DS1087LU-40K is a 3.3V Spread-Spectrum EconOscillator clock generator manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.7V to 3.6V and supports an output frequency of 40 MHz. The device features a maximum input frequency of 400 kHz and maintains a duty cycle of up to 55%. It draws a typical operating current of 15 mA and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates spread-spectrum clock generation capabilities to reduce electromagnetic interference.
• Operates as a standalone oscillator with programmable frequency outputs.
• Supports low-voltage operation suitable for portable and battery-powered applications.

Applications

• Clock generation for digital signal processing systems
• Timing sources for embedded microcontroller interfaces
• Electromagnetic interference reduction in high-speed data transmission lines

Procurement Notes

Verify the specific suffix (e.g., T, +) against the official datasheet to ensure correct packaging and lead-free compliance. Confirm availability status through authorized distributors, as supply constraints may apply. Cross-reference the manufacturer part number with equivalent listings to avoid counterfeit components during acquisition.

Selection Notes

Select this component when a precise 40 MHz spread-spectrum clock source is required for 3.3V logic systems. Ensure the design accommodates the specified input frequency limits and thermal operating range. Consider the uSOP-8 package dimensions for PCB layout compatibility and verify interface requirements against system architecture constraints.

Part Context

This model belongs to the DS1087LU series of EconOscillators designed for cost-effective timing solutions. It replaces traditional crystal oscillators by integrating frequency synthesis on a single chip. The series is optimized for applications requiring jitter attenuation and EMI suppression without external passive components.

Replacement Considerations

DS1087LU-40K+T is a verified substitute variant offering identical electrical specifications with tape-and-reel packaging for automated assembly processes.
