DS1086LU+

Overview

The DS1086LU+ is a 3.3V programmable clock generator producing spread-spectrum square-wave outputs from 130kHz to 66.6MHz. It reduces radiated emissions via selectable dithering of 0.5%, 1%, 2%, 4%, or 8% below the programmed frequency. The device features a 2-wire serial interface, glitchless output-enable control, and power-down mode. All settings are stored in nonvolatile EEPROM for standalone operation. It operates on a 2.7V to 3.6V supply within the industrial temperature range of -40°C to +85°C.

Feature Summary

• Spread-spectrum output with selectable dither magnitudes: 0.5%, 1%, 2%, 4%, or 8%
• Programmable frequencies from 130kHz to 66.6MHz with 5kHz master step size
• Nonvolatile EEPROM storage for all configuration settings
• Glitchless output-enable and power-down modes

Applications

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

Procurement Notes

Verify the component is lead-free/RoHS-compliant as indicated by the '+' suffix. Confirm the package type is 8-pin µSOP (118 mils). Check that the operating temperature range matches the industrial specification (-40°C to +85°C). Ensure the supply voltage requirements align with the 2.7V to 3.6V range.

Selection Notes

Select this component when EMI reduction through spread-spectrum clocking is required. It is suitable for applications needing a single-output clock generator without external timing components. Consider the 2-wire interface for system integration and the nonvolatile memory for maintaining settings across power cycles.

Part Context

The DS1086LU+ belongs to the DS1086L EconOscillator family. It is a 3.3V variant designed for industrial temperature ranges. The 'LU' designation specifies the 8-pin µSOP package. The '+' indicates compliance with lead-free and RoHS standards.
