DS1021S-25

Delay lines play a significant role in providing periodic and delayed triggering of input signals. The DS1021S-25 is an adjustable delay line, suitable for a variety of applications and working scenarios where consistent timing and output accuracy is required. Using this device, it is possible to generate a delay of 1.25 to 128 microseconds in several different formats including single pulse, fixed, variable and programmable.

The device is composed of a 25 stage telescoping array of inverting delay cells. Each stage results in a delay of 5 nanoseconds. The overall delay is determined by a count value. This count is purpose driven in order to convert the counts into an equivalent microsecond delay. The maximum delay of 128 microseconds is due to the limitation of the count range of 255. It is possible to increase this upper limit by connecting two DS1021S-25s together.

The DS1021S-25 is capable of producing single-pulse, delayed-pulse, fixed-delay mode, variable-delay and programmable-delay outputs. The desired output is selected by jumper-selectable options for the count and programming. The device is designed to minimize the synchronization jitter and settling times. The device also boasts a tight transition time of 5 nanoseconds and an accuracy of 10 ns per count.

In terms of power consumption, the device operates on a 5V DC supply, with a typical power consumption of 100 mW. The device also offers a power-down feature, which can save 30 mA when activated. The output is available in various formats, including single ended and differential.

DS1021S-25 can therefore be used in a range of applications, particularly ones where consistent timing and accuracy are essential. These include the development of test and measurement systems, datacomm and video applications. In medical systems it can be used as trigger-delay device to automate ultrasound scanners and other imaging systems. It can also be used in communications systems such as GPRS networks and base stations. Other applications include automotive applications such as airbag systems and ABS brakes.

In conclusion, the DS1021S-25 is a highly accurate and reliable adjustable-delay device which is suitable for a large range of applications where high accuracy timing or triggering is required. With its wide range of settings and adjustable delays, the device offers users a great deal of flexibility when creating their applications.
