The DS1013S-20 is an adjustable delay line from Maxim Integrated. It is a unique clock and timing component that is used to delay a incoming signal by either a fixed, or a variable amount of time. It is built from a series of low-power, low-jitter delay cells, with a linear voltage-controlled delay line for fine adjustment in between. Using the DS1013S-20 chip, a wide variety of applications and timing requirements can be achieved with the utmost accuracy.

Delay lines are an essential component in digital and analog circuitry, used to introduce offset timings in order to achieve desired results. The DS1013S-20 aims to provide a more accurate and reliable clock and timing solution to designers. It features a 10.24ns ~ 10.2µs delay period range, using the adjustable voltage control line. This allows for rapid changes in timing, such as when introducing new signals, without the risk of introducing jitter or other timing irregularities.

To aid in the operation of the DS1013S-20, issues such as temperature stability and system accuracy are taken into consideration. Its embedded linear voltage control range from 0V to 3.3V, with a 0.89μs bin resolution that results in a 0.9μs/V tuning rate. This will ensure that no matter what changes appear on the underlying frequencies, the DS1013S-20 will keep accurate. It also has a wide voltage range of 2.7V to 5.5V in order for designers to account for fast changes in system requirements.

How does it work?

The DS1013S-20 features a series of low-power, low-jitter delay cells. A clock signal is applied at the input of this cellular array, which will make it pre-determine the output time delay. It then has a voltage-controlled delay line within itself, which accommodates more precise timing and delay variance. This is done by the application of a voltage pulse, usually between 0V and 3.3V, sent at the output enable line. This will determine the exact sampling period needed for the digital signal part of the output.

The time delay factor of this component is also temperature-compensated, helps ensure accuracy across all temperature ranges. This is especially important for ultra-high-speed operations, as varying temperature may cause timing inaccuracies on the DS1013S-20. To counter this, a temperature compensating network is integrated into the chip, that ensures synchronized timings across different temperature ranges.

Applications of the DS1013S-20

The DS1013S-20 can be used for a wide variety of clock and timing applications, such as for:

• Serial data communications
• High-speed data acquisition systems
• Data routing between clock and data
• Digital/analog synchronous measurements and test equipment
• Embedded servo systems
• Testing of digital circuits
• Pulse rate demodulation
• Fiber optic signals processing
• High-speed analog and digital audio systems
• Timing critical communication protocols

In these applications, clock and timing are of paramount importance. The DS1013S-20 aims to provide an reliable and adjustable component that answers these needs and requirements. With its wide voltage range and temperature compensation features, the component ensures accuracy and stability that designers seek, while allowing them to introduce any delay desired.
