DS1100Z-20 is a delay line product manufactured by Dialog Semiconductor, focused on applications and product features  that use timing and clock generation technologies. It is a delay line based on a digitally controlled solenoid timing circuit.

The goal of the DS1100Z-20 is to match the timing of existing clock domain signals, such as those necessary for embedded microprocessors and other complex clock-driven system designs. By controlling the delay between two clock domains, it is possible to synchronize their signals and consequently create a more stable and reliable system.

The DS1100Z-20 Delay Line is primarily used to align a reference clock signal with a pair of independent external clock signals in order to reduce the jitter due to discrepancies in timing between the two signals. It does this by providing delay adjustment capability for the reference clock relative to the incoming clock signals.

The DS1100Z-20 implements a digitally-controlled delay line that is composed of a chain of capacitive elements, each with a series resistor, connected in a cascade configuration. The resistor values of each element in the delay line are stored in a time-compensated non-volatile register.

The delay line is controlled by a microcontroller that handles the control of the resistor values and the timing of the delay line. The microcontroller is capable of adjusting the delay values in response to a digital input signal, allowing for finer control of the timing of the output clock signal.

The digitally-controlled delay line of the DS1100Z-20 allows users to control the exact desired clock delays to the nanosecond order of magnitude. By utilizing the right combination of resistor values, the delay line can be configured to deliver precise second, millisecond, and nanosecond delays.

The DS1100Z-20 also features a temperature compensation feature, which helps reduce noise and voltage drifts, ensuring accurate timing. Additionally, the device uses low-noise technology and consumes minimal power, making it ideal for battery-powered applications.

The DS1100Z-20 can be used in a wide range of applications such as clock synchronization in IoT, embedded and automotive systems, clock jitter refining for electronic instrumentation, and precise timekeeping for industrial control systems. It is ideal for use in applications that require precise clock timing and precise control of the delay line.

In summary, the DS1100Z-20 is a delay line product designed to match the timing of existing clock domain signals. Using a digitally-controlled delay line composed of a chain of capacitive elements and a microcontroller, it provides users with nanosecond-level delay adjustment capability, precise second, millisecond, and nanosecond delays, and low-power consumption.
