DS1123LE-100+

Delay Lines IC Overview

The DS1123LE-100+ is an 8-bit programmable timing element operating on a single 3.3V supply within the 0°C to +70°C temperature range. It provides 256 delay steps with a typical step size of 1ns, achieving a maximum delay of 255ns relative to the reference output. The device supports parallel and 3-wire serial programming interfaces, features guaranteed monotonicity, and includes an on-chip reference delay for phase adjustment.

Delay Lines IC Feature Summary

• Configurable as a delay line, monostable vibrator, or free-running oscillator
• Supports both parallel and 3-wire serial programming interfaces
• Includes an on-chip reference delay to offset inherent step-zero delay

Delay Lines IC Applications

• Telecommunications
• Digital Test Equipment
• Signal Generators and Analyzers

Delay Lines IC Procurement Notes

Verify the component against official manufacturer documentation to confirm authenticity and specifications. Ensure that the ordering suffix matches the required performance grade and package type. Cross-reference part numbers with authorized distributors to ensure compliance with current manufacturing standards.

Delay Lines IC Selection Notes

Select this model when a 1ns step size and up to 255ns total delay are required. Verify that the system operates within the specified 3.0V to 3.6V voltage range and 0°C to +70°C temperature limits. Consider the 16-pin TSSOP package dimensions for PCB layout constraints.

Delay Lines IC Part Context

This component belongs to the DS1123L family of 3.3V programmable timing elements. It functions similarly to the DS1023 but is optimized for lower voltage operation. The device allows signal delays exceeding a full period, enabling complete 360-degree phase shifting capabilities in digital systems.
