Delay Lines IC Procurement Notes

Verify the component against official Maxim Integrated datasheets to confirm pinout compatibility and electrical specifications. Ensure that the 3.3V power supply requirements and operating temperature limits align with your system design constraints before finalizing procurement decisions.

Delay Lines IC Selection Notes

Select this model when a 0.5ns resolution is required for precise timing adjustments. Consider the 16-pin TSSOP package dimensions for PCB layout. Evaluate whether the 3-wire serial interface meets your microprocessor I/O resource limitations compared to the parallel option.

Delay Lines IC Part Context

This component belongs to the DS1123L family of 3.3V programmable timing elements. It shares functional similarities with the DS1023 but is optimized for lower voltage operation. The 'E' suffix indicates the specific speed grade with a 0.5ns step size, distinguishing it from other variants in the series.

Delay Lines IC FAQ

How does the DS1123LE-50+ handle phase shifting?

It can shift a clock signal over the full 0 to 360° phase range by delaying signals by a full period or more.

What is the purpose of the REF/PWM pin?

It serves as a reference output to offset inherent step-zero delay or acts as a PWM output in monostable mode.
