DS1023S-200+T&R

Overview

The DS1023S-200+T&R 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 2ns, yielding a maximum delay time of 510ns. The device supports both parallel and serial programming modes via dedicated control pins. It includes an on-chip reference delay output to compensate for inherent step zero delays. The component is housed in a 16-pin SOIC package and is rated for operation within a 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 offset 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 applications requiring variable delay
• Pulse width modulation signal generation
• Free-running oscillator circuits
• Timing element configuration in digital systems

Procurement Notes

Verify the specific suffix (+T&R) against official documentation to confirm tape-and-reel packaging requirements. Ensure the ordering part number matches the exact step size variant required for the design. Confirm RoHS compliance status through the manufacturer's current environmental declarations before finalizing procurement orders.

Selection Notes

Select this model when a 2ns step size and up to 510ns total delay are required. Consider the DS1023S-100+T for finer resolution or the DS1023S-500+T&R for longer delay ranges. Verify that the 16-pin SOIC package fits the PCB layout constraints. Ensure the application voltage remains within the specified 4.75V to 5.25V range for optimal performance.

Part Context

This component belongs to the DS1023 family of 8-bit programmable timing elements. It shares functional similarities with the DS1020 and DS1021 but offers revised internal architecture for extended delay capabilities. The 'S' designation indicates the SOIC package variant, while the '-200' suffix specifies the 2ns step size characteristic unique to this model within the series.

Replacement Considerations

Direct substitutes include other variants within the DS1023 family such as DS1023S-25+T, DS1023S-50+T, DS1023S-100+T, and DS1023S-500+T, depending on required delay resolution. Cross-family replacements like the DS1020 or DS1021 may be considered if pin compatibility and programming logic align with the existing design constraints.
