DS1023S-500

Overview

The DS1023S-500 is an 8-bit programmable timing element manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single 5V supply (4.75V to 5.25V) and features a delay step size of 5ns with a maximum delay time of 1275ns. The device supports both parallel and serial programming modes, allowing flexible configuration for various timing applications. It is housed in a 16-pin SOIC package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Configurable as a delay line, pulse width modulator, or free-running oscillator
• Includes an on-chip reference delay to compensate for inherent step zero delay
• Supports both parallel and serial programming interfaces
• Capable of delaying clocks by a full period or more

Applications

• Clock phase control
• Pulse width modulation
• Free-running oscillation

Procurement Notes

Verify the specific suffix and packaging type when ordering, as availability may vary. Confirm that the component meets RoHS compliance requirements if necessary for your application. Ensure that the voltage and temperature specifications align with your system design constraints before finalizing procurement.

Selection Notes

Select the DS1023S-500 when a delay step size of 5ns is required. Consider the maximum delay time of 1275ns for your timing needs. Ensure compatibility with the 16-pin SOIC package and single 5V supply requirement. Verify programming mode support for your interface.

Part Context

The DS1023 series includes variants like the DS1023-25, -50, -100, and -200, each offering different delay step sizes ranging from 0.25ns to 2ns. The DS1023S-500 specifically provides a 5ns step size, making it suitable for applications requiring coarser delay adjustments compared to other members of the family.

Replacement Considerations

Direct replacements within the DS1023 series include DS1023-25, DS1023-50, DS1023-100, and DS1023-200, depending on the required delay step size. Ensure that any substitute part matches the package type and electrical specifications of the original component.
