DS1086U+T

Overview

The DS1086U+T 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 and includes nonvolatile EEPROM storage for standalone operation. The device operates on a 5V supply with a typical active current of 35mA and standby current of 35µA. It utilizes a 2-wire serial interface for configuration and offers glitchless output enable and power-down controls.

Feature Summary

• Programmable frequency range from 260kHz to 133MHz with 10kHz step size
• Selectable 2% or 4% spread-spectrum dithering for EMI reduction
• Nonvolatile EEPROM memory retains settings without external power
• Glitchless output enable and dedicated power-down mode

Applications

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

Procurement Notes

Verify the + suffix indicates lead-free/RoHS compliance. Confirm the U package designation corresponds to the µSOP-8 form factor. Check that the T suffix aligns with the manufacturer's specific tape-and-reel packaging requirements for this component variant.

Selection Notes

Select this model for 5V logic systems requiring integrated clock generation without external timing components. Ensure the operating temperature range of 0°C to +70°C meets system environmental constraints. Verify that the 2-wire serial interface voltage levels are compatible with the host microprocessor.

Part Context

This component belongs to the DS1086 EconOscillator family, which integrates a master oscillator, prescaler, and EEPROM into a single chip. The U package variant specifically denotes the µSOP-8 surface-mount housing. The device eliminates the need for discrete crystals or resonators in standard clock distribution applications.

Replacement Considerations

Public confirmed substitute part numbers only; omit otherwise.
