The DS1100LU-25+T is a family of clock and timing delay lines from National Semiconductor, intended for a variety of applications. These unique devices are able to provide precise, programmable delays of up to 25ns. The DS1100LU-25+T can be used in a wide range of applications, such as digital communication systems, signal processors and computer networks, where ultra-precise delay control is critical.

The DS1100LU-25+T consists of an array of memory cells arranged in a linear fashion, along with a user programmable delay line control circuit. The delay line control circuit is responsible for providing exact timings of up to 25ns resolution. Each delay line is individually programmable and can be set to the desired delay range. The DS1100LU-25+T also features three outputs, which can be set to provide different timings when the input signal is active.

The working principle of the DS1100LU-25+T is based on the concept of timing-chain. A timing-chain is a chain of events that occurs in a specific sequence. When the delay line control circuit receives an input signal, the chain of events begins. The delay line control circuit outputs a trigger signal to the first memory cell in the array, which in turn triggers the next cell, and so on. Each memory cell stores a predetermined amount of data and sends a timing signal to the next cell when it is triggered. This process continues until the desired delay has elapsed and the delayed output is produced. The resulting delays are accurate to within 5% of the programmed value.

The DS1100LU-25+T is an extremely versatile device and can be easily integrated into many existing digital systems. It is highly resilient to temperature and supply variations and can tolerate an extended voltage range. The device also provides glitch-free transitions between the input signals and the delayed outputs. Additionally, the DS1100LU-25+T requires very low voltage and power consumption, making it suitable for applications where energy efficiency is a priority. The device is also quartz-lockable, which enables synchronization with other quartz based systems.

Overall, the DS1100LU-25+T provides a unique and highly-flexible solution for applications where ultra-precise timing control is required. Its small size and low power consumption make it an ideal choice for a wide range of applications. The device’s quartz-locking feature also ensures reliable operation in cases where synchronization of multiple systems is critical.
