The 8N4DV85KC-0105CDI programmable timer and oscillator is composed of differential current oscillator, voltage controlled oscillator and delay line. It is an advanced frequency control device and plays a key role in a variety of applications such as communications, instrumentation, audio and video systems.

This highly integrated device utilizes differential current oscillator and voltage-controlled crystal oscillator as its basic elements. It provides a wide variety of frequency ranges from 100 kHz to 1 GHz and has a fast settling time with a maximum cycle time of 50 ns. It is also able to support applications requiring high accuracy with its high stability of 0.2% over a temperature range of -40 to 85°C. It also has low electro-magnetic interference, power consumption and electromagnetic emission.

The 8N4DV85KC-0105CDI can be used in a variety of applications such as frequency synthesis, phase-locked loop or digital signal processing. It also is suited for various system architectures, including but not limited to network systems, broadcast systems, mobile systems and automatic control.

In terms of its working principle, the 8N4DV85KC-0105CDI operates in two modes: a differential current oscillator or voltage controlled oscillator. In both modes, the loop filter, the oscillator, and the delay line interact to generate a reference frequency. The output signal of the oscillator is then fed back to the input of the delay line and the output signal is shifted in phase at the same rate as that of the oscillator.

When the 8N4DV85KC-0105CDI is used as a differential current oscillator, the device senses the potential difference between the two electrode pins, amplifier it and feed back it back to the negative pin. The feedback amplifies the signals to an increasingly higher level until a sustained oscillation is achieved.

In voltage controlled oscillator mode, a voltage applied to the control pin shifts the resonant frequency of the oscillator depending on the applied voltage. When the voltage applied is varied, the frequency output also varies.

The 8N4DV85KC-0105CDI programmable timer and oscillator is a highly advanced frequency control device that is suitable for various applications. With its wide range of frequency range, fast settling time and high stability, it is able to provide highly accurate and reliable results. Its ability to operate in two different modes also allows it to be used in different architectures and applications.
