The DS1100LZ-20 is a precision digital delay line designed for use in a variety of applications as a syncrhonizing, timing, or gating source. The device is suited for high accuracy triggering and delaying of pulses, digital signals or clock pulses. It is also well-suited for a wide range of applications where precise delay times must be accomplished electronically, both in development and production testing.

Overview

The DS1100LZ-20 is a monolithic integrated device with a five-stage programmable delay line. It is characterized by low power consumption, high accuracy, and one-shot operation over a wide range of input and output waveform characteristics.The unit offers unique commands and flexibility with a maximum delay per step of 2048 ns and a maximum output frequency of 400 kHz.It is composed of a five-stage delay line with a synchronous feedback loop with a total delay of up to 10.2 msec.It is designed for accuracy, low skew, and low noise waveforms for single or multiple stages.When it is used as an oscillator, the unit achieves a stable output within 500 ns of settling time.

Applications

The DS1100LZ-20 is designed for a variety of applications, including:

• Video signal processing
• Medical imaging
• Industrial monitoring
• Autonomous control systems
• Telecommunication systems
• Consumer electronics

The device can be used for single and multi-stage trigger and delay events, as well as a synchronizing and timing source. It can be used both in laboratory and process monitoring applications, where precise and repeatable delay times need to be met. The device also has the capability of low jitter delay generation, making it suitable for applications such as image and video processing, test stand synchronization, automation control, and other industrial applications where timing must be maintained within very strict parameters.

Working Principle

At the heart of the DS1100LZ-20 is a digital delay line composed of five chained stages of programmable delay elements (i.e., taps). Each stage can be programmed with an individual delay from 1 μs up to a total 2.048 ms delay. In addition, the device can be programmed with a single or multiple active delay stages.The device is designed for accurate and repeatable output timing. The delay lines are designed with synchronous feedback, so that the output of each stage is the same as its input. This ensures that the output waveform is the same at each stage. The unit operates in one-shot mode, so that once the input is applied, the output waveform is generated within 500 ns of delay.

The unit is driven with a control signal, which may be static or dynamic. A static control signal is used when the delay needs to remain constant - such as in a timing application - while a dynamic control signal allows the delay to be programmable. In dynamic mode, the delay line can be programmed with a variety of waveforms, such as sawtooths, sine wave, and steps. The waveform can be adjusted for the specific application and can be used for controlling the timing of pulse width modulation, waveform fading, or other waveform generation.

The DS1100LZ-20 is designed to be simple to configure and use. The delay programming and output waveforms are controlled with a few digital commands. The unit also provides digital or analog output, as well as buffering and protection, making it especially suitable for driving digital logic or interfacing with other devices.

Conclusion

The DS1100LZ-20 is a versatile digital delay line that can be used in a variety of applications. It offers precision and accuracy, low power consumption, one-shot operation, and a wide range of waveform control. This makes it well-suited for development and production testing, as well as industrial, consumer, and medical applications. The device is easy to configure and provides a simple and reliable solution for precise and critical timing requirements.
