DS1086LU-C02+

Overview

The DS1086LU-C02+ is a 3.3V programmable clock generator from the EconOscillator family, manufactured by Analog Devices Inc./Maxim Integrated. It produces a spread-spectrum square-wave output with frequencies ranging from 130kHz to 66.6MHz. The device features selectable dithered output levels of 0.5%, 1%, 2%, 4%, or 8% below the programmed frequency to reduce radiated-emission peaks. All settings are stored in nonvolatile EEPROM memory for standalone operation. It operates on a 2.7V to 3.6V supply and includes power-down and output-enable controls.

Feature Summary

• Programmable square-wave generator with frequencies from 130kHz to 66.6MHz
• Selectable dithered output (0.5%, 1%, 2%, 4%, or 8%) for EMI reduction
• Nonvolatile EEPROM memory stores all device settings
• 2-Wire serial interface for programming and control

Applications

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

Procurement Notes

Verify the specific C02 suffix configuration against official documentation, as it denotes custom factory-programmed settings. Confirm current availability status directly with the manufacturer or authorized distributors, as lead times and stock levels fluctuate. Ensure compliance with RoHS standards if required for the application.

Selection Notes

Select this component when a low-cost, single-output spread-spectrum oscillator is needed to minimize electromagnetic interference. It is suitable for applications requiring precise frequency generation without external timing components. Consider the 2-Wire interface requirements for system integration and ensure the operating voltage range matches the system's 3.3V logic levels.

Part Context

The DS1086LU-C02+ belongs to the Maxim Integrated DS1086L series of spread-spectrum oscillators. The 'LU' indicates an industrial temperature range (-40°C to +85°C) and an 8-pin µSOP package. The '+C02' suffix specifies a custom frequency and dither setting programmed by the factory, distinguishing it from standard off-the-shelf variants.

Replacement Considerations

Standard replacements include the DS1086LU+ or DS1086LU+T for identical functionality with default factory settings. For custom frequency requirements, contact the manufacturer directly for equivalent custom-ordered parts. Verify pin compatibility and electrical specifications before substituting.
