It can be used as a clock generator to create an accurate and stable clock signal for a range of digital applications, such as microcontroller and digital signal processor (DSP) clocking. It can also be used as a clock buffer to spread the clock signal across a wide range of digital devices. Additionally, the 8N3Q001EG-0091CDI can be used as a clock controller to control the sequencing and delivery of clock signals to multiple devices. For instance, it can be used to precisely synchronize two or more asynchronous clocks with each other, or to produce multiple independent fixed-frequency clocks, such as for identification and communications.

Working Principle

The 8N3Q001EG-0091CDI is a Programmable Delay Line (PDL) device and works on the principle of varying its internal delay cell. The device consists of an array of N repeatable components, each consisting of storage capacitance in the delay path, the primary principle being to vary the effective output of the delay line by changing the values of a series of capacitive elements driving it. Each repeating delay element produces an incremental delay and the device is programmed to produce an output waveform that is controlled by the external input waveform. The waveform is configured by writing the desired output waveform to the external registers.

The 8N3Q001EG-0091CDI operates with a common external clock signal which is connected to all the delay elements. This clock signal is provided to an internal register and is used to synchronize the delay elements of the device and accurately control all of the delay timing parameters. The delay, skew and phase of the output clock waveform are programmable, allowing the device to be adapted to a variety of applications.

Conclusion

The 8N3Q001EG-0091CDI is a highly integrated and versatile programmable delay line device that is suitable for a variety of time-critical applications. Its high accuracy and programmability, along with its wide application field, make it a cost-effective solution for designers seeking to solve their time-critical design challenges.
