DS1004Z-2/T&R

Overview

The DS1004Z-2/T&R is a five-tap all-silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It provides precise tap-to-tap nominal delays of 2 ns with tolerances of ±0.75 ns at +25°C and ±1.5 ns over the operating temperature range of 0°C to +70°C. The device features an input-to-tap 1 delay of 5 ns, operates on a single +5V supply (4.75V to 5.25V), and draws up to 75 mA of active current. Packaged in an 8-pin SOIC (150 mil) format, it supports Tape and Reel delivery.

Feature Summary

• Provides five equally delayed clock phases per input using an all-silicon timing circuit
• Maintains input symmetry through precise leading and trailing edge accuracies
• Features CMOS design architecture with TTL compatibility for versatile logic interfacing
• Capable of driving up to 10 LS loads per output tap

Applications

• High-speed silicon timing circuits requiring precise phase shifting
• Clock distribution networks needing multiple delayed signal phases
• Digital systems utilizing tapped delay lines for synchronization

Procurement Notes

Verify that the ordering suffix /T&R confirms the tape and reel packaging configuration. Confirm the specific part number variant matches the required delay tolerance specifications. Ensure the component meets the necessary environmental and electrical standards for the intended application environment.

Selection Notes

Select this component when a 2 ns tap-to-tap delay is required within the DS1004 family. Compare against other variants like DS1004Z-3 or DS1004Z-4 if different delay increments are needed. Verify that the 8-pin SOIC package fits the board layout constraints and that the operating temperature range aligns with system requirements.

Part Context

This component belongs to the DS1004 series of high-speed silicon delay lines. The 'Z' suffix indicates the 8-pin mini-SOIC package, while the '-2' specifies the 2 ns tap-to-tap delay characteristic. The '/T&R' denotes the tape and reel packaging option for automated assembly processes.

Replacement Considerations

DS1004M-2/T&R offers identical electrical performance but utilizes an 8-pin DIP package instead of the SOIC form factor.
