DS1000Z-125

Overview

The DS1000Z-125 is a nonprogrammable silicon delay line component from the DS1000 series, manufactured by Analog Devices Inc./Maxim Integrated. It provides five fixed taps with a total available delay of 125ns and a tap increment of 25ns. The device operates on a single 5V supply voltage (4.75V to 5.25V) and functions within an industrial temperature range of -40°C to +85°C. It is housed in an 8-pin SOIC package.

Feature Summary

• Provides five independent fixed delay taps for precise timing control
• Utilizes silicon technology for stable signal propagation delays
• Operates with a standard 5V power supply requirement

Applications

• Digital oscilloscope trigger path delay generation
• System clock skew compensation
• Pulse width modulation circuit timing adjustment

Procurement Notes

Verify the specific suffix designation to ensure compatibility with required package types and temperature ratings. Confirm that the nonprogrammable nature aligns with system design requirements, as tap delays are fixed at 25ns increments. Check current availability status as this component family may have limited stock or end-of-life implications.

Selection Notes

Select this component when fixed delay values are sufficient for the application, eliminating the need for programmable logic complexity. Ensure the 125ns total delay range meets the system's maximum timing requirements. Verify that the 8-pin SOIC footprint fits the PCB layout constraints and that the operating temperature range covers the intended environmental conditions.

Part Context

The DS1000Z-125 belongs to the DS1000 series of silicon delay lines, which are designed for high-speed digital applications requiring precise timing adjustments. This series offers various total delay options, with the Z-125 variant providing a compact 125ns delay profile suitable for space-constrained designs.

Replacement Considerations

The DS1000M-125 serves as a direct replacement option, offering identical electrical characteristics but packaged in an 8-pin DIP format instead of SOIC. Both components share the same 5-tap structure and 25ns increment specifications.
