Delay Lines are an important class of components used in contemporary electronics systems. The DS1135U-12 is a particular type of delay line that is commonly used by professionals in the field. This article will discuss the DS1135U-12’s field of application, and its working principle.

Applications

The DS1135U-12, manufactured by Texas Instruments, is a “statement-level pin-programmable delay line designed for precision timing control in automated test systems.” This device is an attractive option for engineers in the areas of communications, aerospace, and defense, among others. According to the company’s product literature, the device is “fully user programmable to generate any fractional delay from 0 to 5 microseconds in 0.125 microsecond increments.” The device is capable of controlling the delay of both digital and analog signals, allowing greater flexibility in the design process.

The DS1135U-12 is a high-accuracy device, with a typical delay-line accuracy of ±1.5% of maximum delay. The device is fairly simple to use, with only a few pins to connect and program, and an input clock of 24.576 MHz. The device also consumes only 1.4 mA of total power when the output drivers are activated.

The delay line can also be used in digital filters, image processing, data compression, and mathematical computations. The high accuracy and relatively low complexity of the DS1135U-12 makes it an ideal choice for many different fields of electronics engineering.

Working Principle

The primary component in the DS1135U-12 is a chain of delay cells, connected in a serial fashion. Each delay cell contains a number of smaller individual stages, each producing a delay of typically 0.125 microseconds. The total delay is determined by the number of delay cells that are cascaded together. The output of each delay cell is fed back into the input of the next cell in the chain, and the number of delay cells is determined by the user’s needs.

The clock signal is supplied to the input of the first delay cell, and the output of the last delay cell is fed into the output channel. The output channel can also be used to supply the input signal to the delay line in a continuous loop, thus allowing for longer delays. The output channel can also be used to supply the input signal to the delay line in a continuous loop, thus allowing for longer delays.

The delay line is then programmed by applying different voltages to the program pins. These pins enable the user to control the delay within the range of 0 to 5 microseconds, in 0.125 microsecond increments. The total delay of the delay line is calculated by summing the delay of each delay cell. The number of cells can also be controlled by enabling or disabling the enable pins.

Conclusion

Although delay lines are a relatively simple circuitry, they are still an important part of contemporary electronics systems. The DS1135U-12 is a particularly versatile and accurate delay line, that offers great performance for a wide range of applications. The device is very user-friendly, requiring only a few pins to control and program. The DS1135U-12 is therefore an ideal choice for many different fields of electronics engineering.
