DS1086LU-B66+

Overview

The DS1086LU-B66+ 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 and glitchless output-enable control. All settings are stored in non-volatile EEPROM for standalone operation.

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%
• Non-volatile EEPROM memory stores all configuration settings
• 2-Wire serial interface for programming and control

Applications

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

Procurement Notes

Verify the specific suffix B66 against official documentation to confirm if it denotes a custom factory setting or standard packaging variant. Contact the manufacturer directly for ordering information and availability status, as distribution channels may vary.

Selection Notes

Select this component when EMI reduction via spread-spectrum clocking is required without external timing components. Ensure the application voltage remains within the 2.7V to 3.6V range and that the 8-pin μSOP package fits the PCB layout constraints.

Part Context

This part belongs to the DS1086L series of 3.3V Spread-Spectrum EconOscillators. The base model DS1086LU is available in an 8-μSOP package with an industrial temperature range of -40°C to +85°C. The '+' indicates lead-free/RoHS compliance.

Replacement Considerations

Direct replacements include other DS1086L variants such as DS1086LU+ or DS1087LU-216, provided the frequency and package requirements match. Verify pin compatibility and register settings before substitution.
