DS1086Z+T&R

Overview

The DS1086Z+T&R is a programmable clock generator from the EconOscillator family, manufactured by Analog Devices Inc./Maxim Integrated. It produces a spread-spectrum square-wave output with frequencies ranging from 260kHz to 133MHz. The device features selectable dithered outputs of 2% or 4% to reduce radiated emissions. It operates on a single 5V supply and includes a power-down mode for energy efficiency. All configuration settings are stored in nonvolatile EEPROM memory, enabling standalone operation without external timing components.

Feature Summary

• Programmable frequency range from 260kHz to 133MHz with 10kHz master frequency step size
• Selectable 2% or 4% spread-spectrum dithering to minimize EMI peaks
• Nonvolatile EEPROM storage for register settings, allowing standalone functionality
• Glitchless output-enable control and dedicated power-down mode

Applications

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

Procurement Notes

Verify the specific suffix requirements for the component. The 'Z' indicates an SOIC-8 package, while '+T&R' denotes lead-free/RoHS compliance and tape-and-reel packaging. Confirm that the operating temperature range of 0°C to +70°C meets the system environmental specifications before procurement.

Selection Notes

Select this component when a programmable clock source with built-in EMI reduction is required. Ensure the design supports a 5V supply voltage and utilizes a 2-wire serial interface for configuration. The device eliminates the need for external crystals or resonators, simplifying the bill of materials compared to traditional oscillator solutions.

Part Context

This part belongs to the DS1086 EconOscillator series, which integrates a voltage-controlled oscillator, prescaler, and digital control logic into a single chip. The Z variant specifically refers to the 8-pin Small Outline (SO) package. The T&R suffix confirms the delivery format as tape and reel, suitable for automated surface-mount assembly processes.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult the manufacturer's official cross-reference tools or contact factory support directly to identify compatible alternatives for legacy or end-of-life scenarios.
