DS1020-100

Overview

The DS1020-100 is a programmable 8-bit silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It provides a nominal step size of 1 ns, resulting in a maximum delay time of 265 ns with an inherent step-zero delay of 10 ns. The device operates on a single +5V supply (4.75V to 5.25V) and supports both parallel and serial programming interfaces. It features TTL/CMOS compatibility and is available in standard 16-pin DIP or SOIC packages.

Feature Summary

• Supports programmable delay values via either an 8-bit parallel port or a 3-wire serial interface
• Provides accurate leading and trailing edge timing reproduction without signal inversion
• Enables daisy-chaining of multiple units for cascaded programming through the serial output pin

Applications

• Precision timing control in digital logic circuits
• Programmable pulse width generation
• Signal synchronization and skew adjustment

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature range. Confirm availability status as distribution channels may vary. Ensure the ordering code matches the required interface configuration and performance specifications before procurement.

Selection Notes

Select the DS1020-100 when a 1 ns resolution is required for delays up to 265 ns. Choose between DIP or SOIC packaging based on board layout constraints. Ensure the design accommodates the necessary setup and hold times for the chosen programming mode.

Part Context

This component belongs to the DS1020 family of all-silicon CMOS programmable delay lines. The series offers various models with different step sizes ranging from 0.15 ns to 2 ns, allowing designers to select the appropriate granularity for their specific timing requirements.

Replacement Considerations

DS1020S-100 is a surface-mount variant within the same functional family.
