DS1086Z+

Overview

The DS1086Z+ is a programmable clock generator producing spread-spectrum square-wave outputs from 260kHz to 133MHz. It features selectable 2% or 4% dithering to reduce radiated emissions. The device operates on a 5V supply with a typical active current of 35mA and includes power-down and glitchless output-enable controls. All settings are stored in nonvolatile EEPROM, enabling standalone operation without external timing components.

Feature Summary

• Programmable frequency range from 260kHz to 133MHz
• Selectable 2% or 4% spread-spectrum dithering for EMI reduction
• Nonvolatile EEPROM storage for standalone configuration
• Glitchless output-enable control and power-down mode

Applications

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

Procurement Notes

Verify the specific package variant required, as the DS1086Z+ denotes an 8-pin SO package. Confirm RoHS compliance status via official documentation. Check for end-of-life notifications or discontinuance notices from Analog Devices/Maxim Integrated before finalizing procurement plans.

Selection Notes

Select this component when a 5V supply is available and spread-spectrum clocking is needed for EMI compliance. Ensure the target frequency falls within the 260kHz to 133MHz range. Verify that the 2-wire serial interface can be accommodated by the system design for programming or if SDA/SCL pins can be tied high for fixed-frequency operation.

Part Context

The DS1086Z+ belongs to the DS1086 EconOscillator family, which integrates a voltage-controlled oscillator and prescaler into a single chip. This series eliminates the need for external crystals or resonators, simplifying PCB layout compared to traditional crystal oscillator solutions.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Consult Analog Devices/Maxim Integrated technical support for direct replacements or pin-compatible alternatives.
