DS1087LU-210+

Overview

The DS1087LU-210+ is a factory-programmed spread-spectrum clock generator producing a square-wave output at 10.0MHz with 2% dither. It operates on a 2.7V to 3.6V supply within the -40°C to +85°C temperature range. The device integrates an internal master oscillator and nonvolatile EEPROM, eliminating external timing components. Configuration is managed via a 2-wire serial interface or hardware pins for power-down and output enable.

Feature Summary

• Factory programmed 10.0MHz output frequency with 2% spread-spectrum dither
• Integrated nonvolatile EEPROM stores settings for standalone operation
• Programmable prescaler allows frequency division down to 130kHz
• Hardware control pins for glitchless output enable and power-down modes

Applications

• Printers
• Copiers
• PCs
• Computer Peripherals
• Cell Phones

Procurement Notes

Verify the component status as discontinued through official Analog Devices channels. Confirm that the specific ordering suffix corresponds to the required tape-and-reel packaging format. Ensure compatibility with existing board layouts before procurement due to end-of-life status.

Selection Notes

Select this part when a fixed 10.0MHz clock source with EMI reduction is required. The 2% dither setting is suitable for standard EMC compliance needs. Verify that the 8-pin µSOP package fits the design constraints and that the 2.7V to 3.6V supply voltage aligns with the system architecture.

Part Context

This component belongs to the DS1087L EconOscillator family, which provides spread-spectrum clock generation without external crystals. The 'LU' designation indicates the industrial temperature range (-40°C to +85°C) and the µSOP package. The '+210' suffix specifies the 10.0MHz frequency and 2% dither configuration.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, direct pin-to-pin replacements must be identified through manufacturer cross-reference tools or by evaluating alternative spread-spectrum oscillators from the same product family.
