Clock/Timing - Delay Lines have been widely used to delay high frequency electronic signals for over a century. The most widely used techniques are based on inductor coils, quartz crystals, and transmission lines. In recent years, delay lines based on Programmable Delay Line Products (PDLPs) have become more widely available, and the DS1100LU-125+ is an industry leading example of this type of product.

The DS1100LU-125+ is a single channel programmable delay line capable of providing signal delays from 0.05 to 625.38ns with a resolution of 0.046ns. It provides a precision measurement of the signal delay using a Charge Coupled Device (CCD) acquisition circuit. This CCD circuit is remarkable for its accuracy and is suitable for applications requiring precise delays in the range of µs. The DS1100LU-125+ has the advantage of being cost-effective, reliable, and has a wide broad range of delay performance.

The application field of the DS1100LU-125+ is varied, ranging from embedded systems to high speed communications. It is also used in a wide range of measurement instruments, including oscilloscopes, signal analyzers, frequency counters, satellite systems, and global positioning systems. The DS1100LU-125+ is also used in calibration systems, medical systems, and automotive systems.

The working principle of the DS1100LU-125+ is based on the charge-coupled device (CCD) acquisition circuit. This technique employs a series of capacitors connected in parallel and is capable of performing a long-term charge storage. The signal delay is then measured by counting the number of cycles through the circuit.

The DS1100LU-125+ consists of two integrated circuits and a functional block diagram, which consists of an analog circuit, an analog-digital converter, and an output control circuit. The analog circuit is designed to detect the input signal and convert it into a digital signal. This digital signal is then sent to the analog-digital converter where it is converted into a digital output. The output control circuit provides a control signal to the output circuit to drive the output. This output control circuit is capable of providing precise and reliable control of the delay time.

The main component of the input phase shift circuit is a windowing filter, consisting of two capacitors and two resistors. The windowing filter is used to ensure that the input signal is correctly shifted in relation to the reference clock. Once the input signal is correctly shifted, the differences between the outputs of the windowing filter are passed through a voltage-controlled variable resistor, and then sent to the analog-digital converter.

The output control circuit serves two purposes. It is used to set the precise delay time for the output signal, and it is also responsible for driving the output signal. The output control circuit consists of a voltage-controlled oscillator (VCO) and a differential amplifier. The VCO is used to generate the output control signal, and the differential amplifier is used to convert the output control signal into a control signal that drives the output. The output control circuit is designed to provide precision control of the output signal.

The DS1100LU-125+ is a highly reliable and cost-effective programmable delay line product with a wide range of delay performance, making it suitable for a variety of applications. It has the capability of providing millisecond delays, making it ideal for high speed communications, embedded systems, and medical systems. By using the charge-coupled device (CCD) acquisition circuit, the DS1100LU-125+ is able to provide accurate and precise delays in the range of µs. The output control circuit provides precise control of the output signal, which is essential for many applications.
