DS1086Z-11D+

Overview

The DS1086Z-11D+ is a programmable clock generator from the DS1086 family, manufactured by Analog Devices (Maxim Integrated). It generates spread-spectrum square-wave outputs ranging from 260kHz to 133MHz. The device features selectable 2% or 4% dithering to reduce radiated emissions. It operates on a 5V supply with a typical active current of 35mA and includes nonvolatile EEPROM storage for settings. Key controls include power-down and glitchless output-enable functions via dedicated pins.

Feature Summary

• Programmable frequency range from 260kHz to 133MHz with 10kHz master frequency step size
• Selectable 2% or 4% peak dithered output for EMI reduction
• Nonvolatile EEPROM memory stores user-programmable settings for standalone operation
• Glitchless output-enable control and low-power shutdown mode

Applications

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

Procurement Notes

Verify the specific suffix '11D+' against official documentation to confirm pinout, package type, and temperature range. Ordering suffixes often denote variations in packaging or environmental ratings that do not alter internal functionality but affect physical integration. Confirm availability status as distribution data may vary.

Selection Notes

Select this component when a 5V supply is required and spread-spectrum clocking is needed to minimize electromagnetic interference. Ensure the target frequency falls within the 260kHz–133MHz range. Verify that the 8-pin SO package fits the PCB layout constraints. Check if the 2-wire serial interface compatibility matches the system controller.

Part Context

This part belongs to the DS1086 EconOscillator series, which are single-output programmable clock generators. The 'Z' suffix typically indicates an 8-pin SO package variant. Other family members include the DS1086U (µSOP) and various voltage variants like the DS1086LU (3.3V).

Replacement Considerations

Direct replacements must match the 5V supply requirement and 8-pin SO package. Consider the DS1086U+ for smaller µSOP footprints if space permits. For 3.3V applications, the DS1086LU series is the appropriate alternative.
