DS1023S-100

Overview

The DS1023S-100+T is an 8-bit programmable timing element manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in a 16-pin SOIC package. It operates on a single 5V supply with a voltage range of 4.75V to 5.25V and functions within a temperature range of 0°C to +70°C. The device features a 1ns step size, allowing for a maximum delay time of 255ns. It supports both parallel and serial programming modes and includes an on-chip reference delay to compensate for inherent step zero delays.

Feature Summary

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

Applications

• Clock phase control applications requiring variable delay
• Programmable delay line circuits for signal processing
• Pulse width modulation generation triggered by input waveforms
• Free-running oscillator configurations using external feedback

Procurement Notes

Verify the specific suffix (e.g., +T) against official documentation to confirm packaging type and lead-free status. Confirm that the manufacturer designation matches current Analog Devices specifications, as product lines may transition between Maxim Integrated and Analog Devices branding. Ensure the component meets RoHS compliance requirements for the intended application environment.

Selection Notes

Select the DS1023S-100 variant when a 1ns resolution is required for precise timing adjustments. Consider the 255ns maximum delay range relative to system clock periods. Evaluate whether the 16-pin SOIC package fits the board layout constraints. Verify that the operating temperature range of 0°C to +70°C aligns with the environmental conditions of the final assembly.

Part Context

The DS1023 series serves as an 8-bit programmable timing element, functionally similar to the DS1020 and DS1021 but with enhanced architecture. This family allows for flexible timing configurations including delay lines and oscillators. The DS1023S-100 specifically provides the 1ns step granularity necessary for high-resolution timing control in digital systems.
