DS1086LU-834+

Overview

The DS1086LU-834+T&R is a 3.3V programmable clock generator from the EconOscillator family, manufactured by Analog Devices/Maxim Integrated. It produces spread-spectrum square-wave outputs ranging from 130kHz to 66.6MHz. The device features selectable dithering of 0.5%, 1%, 2%, 4%, or 8% to reduce radiated emissions. It operates on a 2.7V to 3.6V supply and includes a power-down mode with glitchless output enable. All settings are stored in nonvolatile EEPROM, allowing standalone operation without external timing components.

Feature Summary

• Programmable frequency range from 130kHz to 66.6MHz with 5kHz master frequency step size
• Selectable spread-spectrum dither levels: 0.5%, 1%, 2%, 4%, or 8%
• Nonvolatile EEPROM memory for storing configuration settings
• 2-Wire serial interface for programming registers

Applications

• Printers
• Copiers
• PCs
• Computer Peripherals
• Cable Modems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets. Check current lifecycle status as distribution may be limited. Ensure proper handling for ESD-sensitive components during procurement and storage.

Selection Notes

Select this component when spread-spectrum clock generation is required for EMI reduction in digital systems. Verify that the operating voltage range (2.7V to 3.6V) matches system requirements. Consider the 8-pin μSOP package constraints for PCB layout. Ensure the 2-Wire interface compatibility with the host controller.

Part Context

This part belongs to the DS1086L EconOscillator series, which integrates a voltage-controlled oscillator and prescaler into a single chip. The 'LU' suffix indicates the industrial temperature range (-40°C to +85°C) and the 8-pin μSOP package. The '+T&R' designation specifies lead-free/RoHS-compliant packaging in tape and reel format.

Replacement Considerations

Direct replacements within the same family include other DS1086L variants with different temperature ranges or packages. Cross-family alternatives require verification of pin compatibility, voltage levels, and frequency ranges. Consult manufacturer documentation for specific substitution guidelines.
