DS1044R-20

Overview

The DS1044R-20 is a high-speed silicon delay line manufactured by Analog Devices Inc. under the Maxim Integrated brand. It integrates four independent logic buffered delays within a single package, serving as a 4-in-1 timing solution. The device operates on a +5 Volt supply and utilizes all-silicon timing circuits to ensure stable performance across temperature and voltage variations. It is housed in a standard 14-pin SOIC package with an initial delay tolerance of ±1.5 ns. The component preserves input symmetry through precise leading and trailing edge control.

Feature Summary

• Integrates four independent buffered delay lines in a single package
• Provides stable and precise timing over temperature and voltage variations
• Preserves input symmetry via leading and trailing edge precision

Applications

• High-speed digital signal processing timing alignment
• Precision clock distribution networks
• Data bus synchronization systems

Procurement Notes

Verify current availability status as the DS1044 series may be discontinued or subject to limited stock conditions. Confirm package type and suffix requirements for specific thermal or mechanical needs. Check for authorized distributor channels to ensure component authenticity. Review datasheet revisions for any functional updates prior to integration into new designs.

Selection Notes

Select this component when multiple synchronized delay paths are required without consuming separate IC footprints. Ensure the design environment supports +5V operation and SOIC-14 mounting constraints. Verify that the ±1.5 ns initial delay tolerance meets system jitter specifications. Consider thermal management capabilities inherent to the SOIC package for the target application load.

Part Context

The DS1044 series represents a consolidated timing solution derived from the earlier DS1035 architecture. Manufactured originally by Dallas Semiconductor before its acquisition by Maxim Integrated, these devices remain part of the Analog Devices portfolio. The R-20 suffix typically denotes specific manufacturing lot or revision characteristics within the SOIC-14 form factor.

Replacement Considerations

Direct substitutes include other parts within the DS1044 family such as the DS1044R-18, which shares identical pinouts and functional blocks but may differ in delay tolerance specifications. Designers should verify electrical parameter compatibility before swapping variants.
