DS1020S-100+

Overview

The DS1020S-100+ is a programmable 8-bit silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It provides 256 equal delay steps with an incremental delay of 1 ns and an inherent step-zero delay of 10 ns, resulting in a maximum nominal delay of 265 ns. The device operates on a single 4.75 V to 5.25 V supply within a commercial temperature range of 0°C to +70°C. It supports both 3-wire serial and 8-bit parallel programming interfaces for flexible timing control.

Feature Summary

• Supports dual programming modes via 3-wire serial port or 8-bit parallel port
• Provides accurate leading and trailing edge delay reproduction
• Features TTL/CMOS-compatible logic levels and low-power CMOS design

Applications

• Precision timing circuits requiring adjustable signal delays
• Programmable delay lines for digital system synchronization
• Timing element replacement for hybrid programmable delay lines

Procurement Notes

Verify the specific suffix designation against official documentation to confirm package type and performance grade. Confirm RoHS compliance status through current manufacturer declarations. Check for obsolescence notices as this component may be subject to limited availability or discontinuation.

Selection Notes

Select the DS1020S-100+ when a 1 ns resolution and up to 265 ns total delay are required. Ensure the application environment remains within the specified 0°C to +70°C operating temperature range. Verify that the 5V supply voltage aligns with the system power architecture before integration.

Part Context

This component belongs to the DS1020 series of programmable silicon delay lines. The 'S' suffix indicates the 16-pin SOIC surface-mount package variant. The '-100' designation specifies the model with 1 ns step increments. This series serves as a cost-effective alternative to traditional hybrid delay lines.

Replacement Considerations

Direct replacements include other models from the DS1020 family such as DS1020-15, DS1020-25, DS1020-50, and DS1020-200, which offer different step resolutions ranging from 0.15 ns to 2 ns. Ensure the selected substitute matches the required delay range and interface compatibility.
