DS1086LU-533+W

Overview

The DS1086LU-533+W is a 3.3V programmable clock generator producing spread-spectrum square-wave outputs from 130kHz to 66.6MHz. It reduces radiated emissions by dithering frequency 0.5% to 8% below the programmed value. The device features a 2-wire serial interface for programming and stores settings in nonvolatile EEPROM, enabling standalone operation without external timing components. Operating on a 2.7V to 3.6V supply, it includes power-down and glitchless output-enable controls. The component operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Programmable frequencies from 130kHz to 66.6MHz with 5kHz master frequency step size
• Selectable dithered output (0.5%, 1%, 2%, 4%, or 8%) for EMI reduction
• Nonvolatile EEPROM memory for standalone configuration storage
• 2-Wire serial interface for register programming and address setting

Applications

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

Procurement Notes

Verify the specific suffix '533' against official documentation, as standard listings typically reference the base model DS1086LU+. Confirm lead-free/RoHS compliance indicated by the '+' suffix. Ensure the package type matches the required 8-pin μSOP form factor for the target application design.

Selection Notes

Select this component when spread-spectrum clocking is required to minimize electromagnetic interference in digital systems. The internal master oscillator eliminates the need for external crystals or resonators. Verify that the 2-wire bus architecture fits the system's control interface requirements and that the 3.3V supply voltage aligns with the target platform.

Part Context

This part belongs to the DS1086L EconOscillator family, which integrates a voltage-controlled oscillator and prescaler into a single chip. The 'LU' designation indicates the industrial temperature grade (-40°C to +85°C) and the μSOP package. The 'W' suffix typically denotes a tape-and-reel packaging option, distinct from the tube packaging used for standard units.

Replacement Considerations

The DS1086LU+ serves as the standard lead-free replacement for the base model. For applications requiring different packaging, verify if the reel version is available directly from the manufacturer. No direct cross-model substitutes are documented in the provided datasheet.
