Introduction

The 8N4DV85EC-0126CDI is a programmable timer and oscillator which can be used in a variety of fields. This article will focus on the application fields and working principles of this device, primarily as part of the Clock/Timing - Programmable Timers and Oscillators.

Applications

The 8N4DV85EC-0126CDI can be used for a wide range of applications. It is an ideal choice for customers requiring the synchronous operation of devices with the need to make precise time measurements. This product can be used for basic timing control; for secure communications; for protection and alarm systems; and for pulse-width modulation. The 8N4DV85EC-0126CDI is also used in medical settings and in industrial plants, where its programmable timing and frequency-matching are of great value. It is generally used for waveform generation and as an automatic frequency control using quartz crystal or ceramic resonator oscillators.

Working Principle

The 8N4DV85EC-0126CDI works with a voltage- or temperature-compensated crystal oscillator (VCXO). This is a kind of solid-state device which works according to the principle of piezoelectricity. In this device, the vibrating quartz crystal serves as a source of electrical oscillations. The 8N4DV85EC-0126CDI has a frequency range of 0 Hz to 60 MHz, and it offers a wide range of in-phase/quadrature (I/Q) modulation frequencies over this range. It is also capable of generating frequencies that can be used for monitoring and controlling the output.The 8N4DV85EC-0126CDI is based on a technology called “spread spectrum mode”. This mode utilizes a modulated carrier frequency, with the modulation being done on both the amplitude and the frequency of the carrier frequency. This allows for a wider range of frequencies to be used in a single device.The 8N4DV85EC-0126CDI is further equipped with options like programmable timers and oscillators, such as programmable VCXO and low-power TDC (Time Domain Crystal). These can be used to generate selectable phase-shift frequencies and pulse widths.

Conclusion

In conclusion, the 8N4DV85EC-0126CDI is a versatile device that can be used in a wide variety of applications, making it an ideal choice for customers who need precisely timed and frequency-matched devices. It works with a voltage- or temperature- compensated crystal oscillator, and its spread spectrum technology makes it capable of generating a wide range of frequencies.
