DS1023S-50+T

Overview

The DS1023S-50+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 delay step size of 0.5 ns, yielding a maximum delay time of 127.5 ns. The device supports both parallel and serial programming modes via dedicated control pins. 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 parallel or serial programming interfaces

Applications

• Clock phase control applications requiring full period delays
• Pulse width modulation signal generation
• Free-running oscillator circuits

Procurement Notes

Verify the specific suffix designation against official documentation to confirm package type and temperature rating. Confirm availability status with authorized distributors as supply conditions may vary. Ensure the component meets required RoHS compliance standards for the intended application environment.

Selection Notes

Select this model when a 0.5 ns resolution is required for precise timing adjustments. Consider the 127.5 ns maximum delay limit relative to system clock periods. Evaluate the need for serial versus parallel programming based on interface constraints and update frequency requirements.

Part Context

This component belongs to the DS1023 family of 8-bit programmable delay lines. It shares functional similarities with the DS1020 and DS1021 but includes architectural revisions allowing for extended delay ranges and integrated reference outputs. The 'S' suffix indicates the surface-mount SOIC package variant.

Replacement Considerations

DS1023S-100+T: Offers 1 ns step size with 255 ns max delay. DS1023S-25+T: Provides 0.25 ns step size with 63.75 ns max delay. DS1023S-200+T: Features 2 ns step size with 510 ns max delay. DS1023S-500+T: Utilizes 5 ns step size with 1275 ns max delay.
