DS1020S-200+

Overview

The DS1020S-200+ is a programmable 8-bit silicon delay line in a 16-pin SOIC package. It provides a total delay range of 520 ns with a step size of 2 ns and an inherent step-zero delay of 10 ns. The device operates on a single 4.75V to 5.25V supply and supports both 3-wire serial and 8-bit parallel programming interfaces. It features TTL/CMOS compatibility, low-power CMOS design, and accurate leading/trailing edge timing.

Feature Summary

• Programmable delay via 3-wire serial port or 8-bit parallel port
• Accurate leading and trailing edge timing reproduction
• TTL and CMOS compatible logic levels
• Supports daisy-chaining for multiple device control

Applications

• Precision timing circuits requiring adjustable delays
• Pulse width modulation systems
• Digital signal processing synchronization
• Test and measurement equipment timing elements

Procurement Notes

Verify the specific suffix designation against official documentation to confirm package type and environmental compliance. Confirm that the component meets RoHS requirements if applicable to the target assembly process. Ensure the ordering information matches the exact part number variant required for the design specifications.

Selection Notes

Select this model when a maximum delay of 520 ns with 2 ns resolution is required. Consider the DS1020-15 or -25 variants for applications needing finer delay steps. Verify interface compatibility with the host system's serial or parallel bus architecture before integration.

Part Context

This component belongs to the DS1020 family of all-silicon programmable delay lines. It serves as a reliable alternative to hybrid delay lines, offering economical performance in standard DIP and SOIC packages. The series includes models with varying step sizes from 0.15 ns to 2 ns.

Replacement Considerations

Direct replacements within the same family include DS1020-15, DS1020-25, DS1020-50, and DS1020-100. These share identical pinouts and functionality but differ in delay step size and maximum total delay values.
