DS1010S-250/T&R is a digital delay line device from Texas Instruments. The device is designed for variable frequency clocks and delay lines applications, allowing variable delays from the source clock to the destination clock. This device provides variable delays and clock jitter reduction for critical timing applications up to 25ns, and is suitable for embedded systems and digital signal processors.

The device consists of two parts, the delay line (T&R) and the timing generator (FG). The delay line contains delay elements, multiplexers and latches, while the timing generator is a programmable clock generator that controls the timing elements of the delay line and provides asynchronous and synchronous clock delays. The timing generator can generate a wide range of frequencies, and the delay elements can be configured to either delay a single input pulse or to continuously delay the data.

The working principle of the DS1010S-250/T&R is as follows: the clock signals are first divided into two portions, the faster and slower clocks, through the timing generator. The slower clock is then routed through the delay line and the faster clock is used to control the switching of the multiplexers and latches in the delay line. The timing generator then outputs a delayed clock, with a variable delay determined by the delay element timing parameters. The delayed clock is used to control any external logic or memory elements that need to be synchronised with the source clock.

Applications for DS1010S-250/T&R devices include variable frequency clocks, such as those commonly used in digital audio and video systems, and also synchronised memory and logic elements. The device can be used in telecommunications, medical and industrial systems, where timing accuracy and reliability are critical. The device can also be used in computer systems, where variable delays enhance system performance.

DS1010S-250/T&R devices are easy to use, reliable and flexible. The delay elements are standard ASIC components, so they can easily be integrated into existing systems. The timing generator provides a wide range of clock frequencies, and the delay elements can be used to create custom pulse delays or to continuously delay the data. The delay line also ensures that the timing signals are jitter reduced, ensuring that accurate timing signals are provided for critical applications.

In conclusion, the DS1010S-250/T&R device is an ideal tool for digital delay line applications, providing variable delays and jitter reduction for critical timing applications. The device can be easily integrated into existing systems, and provides a wide range of clock frequencies, allowing for custom pulse delays and continuous delay data. Additionally, the device is reliable and flexible, making it an excellent choice for embedded systems, digital signal processors and other timing critical applications.
