DS1000H-35

Overview

The DS1000H-35 is a five-tap silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.75V to 5.25V and features a fixed delay of 35ns from the input to the first tap, with subsequent taps providing incremental delays. The device supports independent delay paths and is designed for surface-mount installation in an SOIC-8 package. It functions reliably across a temperature range of -40°C to +85°C, making it suitable for precision timing applications requiring stable signal propagation characteristics.

Feature Summary

• Provides precise digital delay functionality through five distinct output taps
• Operates on standard 5V logic supply levels for compatibility
• Utilizes compact surface-mount packaging for automated assembly

Applications

• Signal synchronization in high-speed data transmission systems
• Timing adjustment in pulse generation circuits
• Delay compensation in communication interface modules

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific tape-and-reel versus tube packaging requirements prior to ordering. Ensure that the selected variant matches the required thermal and electrical specifications for the target application environment to avoid performance discrepancies.

Selection Notes

Select this component when fixed, non-programmable delay intervals are required for signal integrity management. Consider the SOIC-8 footprint constraints and thermal dissipation capabilities during PCB layout. Evaluate the 35ns base delay against system timing budgets to ensure adequate resolution for phase alignment tasks without introducing excessive latency.

Part Context

This part belongs to the DS1000 series of analog delay lines, which are engineered for applications demanding accurate time-delay generation. The series offers various tap counts and delay values to accommodate different circuit requirements. As a specialized timing element, it complements clock distribution networks and data acquisition systems where precise temporal separation of signals is critical for proper operation.

Replacement Considerations

Direct substitutes include other variants within the DS1000 family such as DS1000H-125 or DS1000Z-40, provided the delay value and pinout compatibility align with the design. Cross-reference datasheets to verify voltage ranges and package dimensions before implementing any alternative components.
