DS1086LU+T

Overview

The DS1086LU+T is a 3.3V programmable clock generator producing spread-spectrum square-wave outputs from 130kHz to 66.6MHz. It features selectable dithering of 0.5%, 1%, 2%, 4%, or 8% to reduce radiated emissions. The device operates on a 2.7V to 3.6V supply with a typical active current of 10mA and standby current of 10μA. Settings are stored in nonvolatile EEPROM, allowing standalone operation without external timing components. It supports industrial temperatures from -40°C to +85°C.

Feature Summary

• Programmable output frequencies from 130kHz to 66.6MHz using internal master oscillator
• Selectable spread-spectrum dither levels: 0.5%, 1%, 2%, 4%, or 8%
• Nonvolatile EEPROM storage for register settings enabling standalone mode
• 2-Wire serial interface for configuration and address setting

Applications

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

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as indicated by the '+' designation. Check lead time availability directly with Analog Devices or authorized distributors due to potential supply constraints.

Selection Notes

Select this component for applications requiring EMI reduction through frequency dithering. Ensure the required output frequency falls within the 130kHz to 66.6MHz range. Verify that the system voltage aligns with the 2.7V to 3.6V operating range. Consider the 8-pin μSOP package dimensions for PCB layout constraints.

Part Context

This part belongs to the Maxim Integrated DS1086L EconOscillator family. It is a specialized silicon oscillator designed to replace crystal resonators while providing spread-spectrum capabilities. The '+T' suffix denotes a lead-free/RoHS-compliant version supplied in tape-and-reel format.

Replacement Considerations

Direct pin-compatible replacements within the same family include the DS1086LU (non-RoHS) or DS1086LPMB1 (Peripheral Module). Cross-family substitutes like the DS1080LU+ offer similar functionality but may require different programming algorithms.
