Introduction

DS1135LU-20+ is a Delay Line from Analog Devices. The DS1135LU-20+ is an ultra high Linearity delay line designed to generate precise delays. It provides a high level of linearity over a wide range of temperatures, while providing one of the lowest levels of noise and distortion on the market. This make the DS1135LU-20+ a viable choice for applications such as communications, instrumentation, and word synchronization.

Applications

The DS1135LU-20+ is commonly used in applications such as Time Division Multiplexers (TDM), Gigabit Ethernet, Fibre Channel, 10G Ethernet, Wireless, Synchronous Optical Networking (SONET), and digital subscriber line (DSL) systems. It is also used for phased array communications, avionics, and test equipment. These applications require a high degree of linearity which the DS1135LU-20+ is capable of providing. The DS1135LU-20+ offers high linearity, low noise, low distortion, and excellent phase noise suppression. This makes it suitable for a wide range of applications, from low-cost devices to high-end systems.

Working Principle

The DS1135LU-20+ employs a variable gain slicing technique to achieve enhanced linearity over temperature. The variable gain slicing approach allows the device to provide a linear delay, with low levels of distortion and noise, over a wide range of temperatures. The DS1135LU-20+ is designed to provide an eight-bit precision delay line. It consists of two eight-bit registers, and each register contains one delay element. The second register is used to store the user-defined time delay. When the delay time is set, the DS1135LU-20+ builds the output signal by combining the input signal and the second register signal. The DS1135LU-20+ can be programmed to provide a delay between 0 and 1023 clock cycles, with a resolution of 8 bits. The DS1135LU-20+ has an integrated multiplexer that controls the order in which the data is taken from the registers. The multiplexer allows the user to select the order of the output signal, allowing for a variety of different delay lines. The multiplexer also allows the user to select the delay accuracy, and the maximum input frequency of the device. The DS1135LU-20+ can be used to generate precise delays with high linearity, low noise and distortion, and excellent phase noise suppression. It provides a low-cost solution for applications that require precise and linear delays, such as TDM, Gigabit Ethernet, Fibre Channel, 10G Ethernet, Wireless, Synchronous Optical Networking (SONET) and digital subscriber line (DSL) systems.

Conclusion

The DS1135LU-20+ is a high performer delay line from Analog Devices. It offers high linearity, low noise, low distortion and excellent phase noise suppression, making it suitable for a wide range of applications. It is commonly used for applications such as Time Division Multiplexers (TDM), Gigabit Ethernet, Fibre Channel, 10G Ethernet, Wireless, Synchronous Optical Networking (SONET) and digital subscriber line (DSL) systems. The DS1135LU-20+ employs a variable gain slicing technique to achieve enhanced linearity over temperature and offers precise delays with maximum input frequency up to 818 MHz.
