DS1023S-100+

Overview

The DS1023S-100+T 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 1ns step size with a maximum delay of 255ns. 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 (+T) indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official documentation. Check current availability as distribution may vary. Ensure the component matches the exact part number for intended application requirements.

Selection Notes

Select this model for applications requiring precise 1ns resolution timing adjustments. Consider the 16-pin SOIC package for surface mount implementations. Evaluate power consumption and interface requirements against system constraints. Verify compatibility with existing clock frequencies and signal levels.

Part Context

This component belongs to the DS1023 series of programmable delay lines. It shares functional similarities with the DS1020 and DS1021 but offers enhanced features such as extended delay ranges and improved architecture. The series provides versatile timing solutions for digital systems.

Replacement Considerations

Direct substitutes include other models within the DS1023 family, such as DS1023-25, DS1023-50, DS1023-200, and DS1023-500, depending on required step size and delay range. Ensure pinout and electrical characteristics match before substitution.

FAQ

What is the maximum delay time for the DS1023S-100+?

The maximum delay time is 255ns, calculated based on the 1ns step size and 8-bit resolution.

How does the on-chip reference delay function?

The reference delay compensates for the inherent step zero delay, allowing relative timings down to zero or less when used correctly.

Can the device be used as a free-running oscillator?

Yes, by connecting the inverted output externally to the input, the device can function as a free-running oscillator.
