DS1086Z-450+

Overview

The DS1086Z-450+ is a programmable spread-spectrum clock generator from the DS1086 series, manufactured by Analog Devices (Maxim Integrated). It produces dithered square-wave outputs ranging from 260kHz to 133MHz. The device features selectable 2% or 4% frequency dithering to reduce radiated emissions. It 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, allowing standalone operation without external timing components.

Feature Summary

• Programmable output frequencies from 260kHz to 133MHz with 10kHz master frequency step size
• Selectable 2% or 4% peak dither for EMI reduction
• Nonvolatile EEPROM storage for register settings
• Glitchless output-enable control and power-down mode

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets. Check for end-of-life notifications as discontinuance may affect long-term availability. Ensure ordering suffixes match required package types and temperature ranges.

Selection Notes

Select based on required output frequency range and dither percentage. Verify voltage compatibility with 5V systems. Consider package type (SOIC-8) and operating temperature range (0°C to +70°C). Evaluate interface requirements for 2-wire serial programming if dynamic configuration is needed.

Part Context

The DS1086Z-450+ belongs to the DS1086 EconOscillator family. It is part of Maxim Integrated's spread-spectrum clock generator lineup designed for EMI mitigation in digital systems. The 'Z' indicates an SOIC package, and '+T' denotes tape-and-reel packaging.

Replacement Considerations

Consult official documentation for cross-reference information. Verify pinout compatibility and electrical specifications before substitution. Check for updated versions within the same product family.
