DS1040Z-A20+

Overview

The DS1040Z-A20+ is a programmable delay line integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It features five independent taps with a total available delay of 20 nanoseconds and a tap increment of 4 nanoseconds. The device operates on a single supply voltage ranging from 4.75V to 5.25V. It supports a single emitter configuration and is housed in an 8-SOIC package with a width of 3.90mm. The component is designed for precise timing applications within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Provides five independent programmable delay taps for precise signal timing control
• Supports single emitter configuration for flexible clock distribution
• Operates within a standard 5V supply voltage range

Applications

• Clock skew compensation in high-speed digital systems
• Timing alignment in data acquisition circuits
• Signal path delay adjustment in communication interfaces

Procurement Notes

Verify the specific suffix A20+ to confirm the 20ns total delay specification, as other variants exist within the DS1040 family. Confirm the 8-SOIC package dimensions match the design footprint requirements. Check current availability status as some older timing components may have limited stock or end-of-life considerations.

Selection Notes

Select this component when a fixed 20ns total delay with five discrete steps is required. Ensure the system operates at 5V logic levels. Consider thermal management if ambient temperatures exceed 70°C, as the commercial grade rating does not support higher extremes. Verify that the single emitter output capability meets the driving requirements of the downstream circuitry.

Part Context

The DS1040 series comprises programmable delay lines designed for timing-critical applications. The DS1040Z-A20+ specifically offers a 20ns delay range, distinguishing it from other variants like the 75ns or 250ns models. It belongs to the broader Maxim Integrated portfolio of precision timing solutions used in industrial and consumer electronics.

Replacement Considerations

Direct substitutes include other DS1040Z variants such as DS1040Z-75+ or DS1040Z-250+, provided the delay requirements differ. Generic replacement requires verifying pin compatibility and electrical characteristics against the original datasheet specifications.
