DS1100LZ-250+

Clock/Timing - Delay Lines

DS1100LZ-250+ is a type of delay line that specializes in precise clock and timing applications, such as clock synchronizers, digital delay lines, and programmable delay lines. A delay line is an electronic device that produces a predefined delay between an input signal, typically a clock, and its output. The precise timing of the output signal with respect to the input is what makes this type of delay line so important. The DS1100LZ-250+ features a 250 ns delay and precise timing accuracy of ±50 ps.

Applications

The precise timing accuracy of the DS1100LZ-250+ makes it ideal for various clock-related applications. For example, it can be used in frequency synchronization applications, such as clock network distribution, AV/C audio, video and data transmission systems, tracking systems, clock and data recovery, PLL synchronization, modeling, simulation and test systems. It can also be used as a programmable delay line in digital systems. Additionally, the DS1100LZ-250+ is JITC compliant, making it suitable for use in military and aerospace applications.

Working Principle

The DS1100LZ-250+ is a delay line that utilizes a 9-bit PROM (Programmable Read-Only Memory) technology to store 9-bit data that is used to control the delay time. The delay lines consist of two stages, an input stage and an output stage. The input stage is responsible for providing the clock signal to the PROM. After the clock signal passes through the PROM, the data is reconstructed and applied to a phase locked loop (PLL) circuit. The output stage is responsible for multiplying the output frequency of the PROM to match the desired output frequency. The delay line\'s precision timing accuracy is achieved by the highly accurate time intervals generated by the PLL.

Conclusion

In summary, the DS1100LZ-250+ is a clock/timing delay line specifically designed for precise and accurate timing applications. It features a 250 ns delay and precise timing accuracy of ±50 ps, making it suitable for frequency synchronization, clock network distribution, digital systems, and military/aerospace applications. Additionally, it utilizes a 9-bit PROM technology and a PLL circuit to accurately control the timing of the output signal relative to the input signal.
