DS1023S-50/T&R

Overview

The DS1023S-50/T&R is an 8-bit programmable timing element manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single 5V supply with voltage limits of 4.75V to 5.25V and functions within a temperature range of 0°C to +70°C. The device features a delay step size of 0.5 ns, providing a maximum delay time of 127.5 ns. It supports both parallel and serial programming modes via an 8-bit interface. The component is housed in a 16-pin SOIC package and includes an on-chip reference delay for accurate phase control.

Feature Summary

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

Applications

• Clock phase control applications requiring variable delay
• Pulse width modulation signal generation
• Free-running oscillator circuits using external feedback connections

Procurement Notes

Verify the specific suffix 'T&R' indicates tape and reel packaging when sourcing components. Confirm that the 'S' designation corresponds to the SOIC package variant required for surface mount assembly. Ensure the operating environment remains within the specified 0°C to +70°C range to maintain guaranteed performance parameters.

Selection Notes

Select this model when a 0.5 ns resolution is required for timing adjustments. Compare against other DS1023 variants based on necessary maximum delay ranges and input frequency constraints. Ensure the system design accommodates the single 5V supply requirement and utilizes the appropriate programming mode for the application's update frequency needs.

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 offers extended capabilities such as clock delays exceeding one full period. The series provides various step sizes to accommodate different timing precision requirements across diverse electronic designs.

Replacement Considerations

Direct substitutes include other models within the DS1023 family, such as the DS1023-25, DS1023-100, DS1023-200, and DS1023-500, which offer different step sizes and delay ranges while maintaining pin compatibility.
