In particular, 8N3DV85KC-0056CDI8 Programmable Timers and Oscillators provide a unique set of features and capabilities for applications requiring high performance and excellent performance stability.

Application Fields:

The 8N3DV85KC-0056CDI8 Programmable Timers and Oscillators are designed primarily for use in computer system components such as mainboards, power supply units and clock oscillators. Additionally, the device can be used with microcontroller-based applications in industrial automation, automotive, consumer, and security monitoring. Furthermore, 8N3DV85KC-0056CDI8 can be useful for aerospace and satellite applications and wherever a compact, reliable and accurate timing reference is needed.

Working Principle:

At its core, 8N3DV85KC-0056CDI8 is a digital programmable oscillator. It uses a digital phase-locked loop (DPLL) to generate frequencies up to 8 GHz, with a period accuracy of up to 30 ppm over the operating temperature range. It also includes a loop filter, an anti-phase fence, an open-drain buffer, and a voltage controlled oscillator.

The oscillator generates a time base signal from the internal quartz crystal oscillator reference with a programmable frequency accuracy (dependent on the crystal accuracy). The oscillator then uses the DPLL to correct the frequency variations that occur as a result of temperature changes or other environmental influences.

The 8N3DV85KC-0056CDI8\'s anti-phase fence permits the DPLL to operate even if any DC component exists in the input signal. This feature enhances the DPLL’s ability to accept the input when the crystal oscillator frequency is slightly off. The open-drain buffer enables the oscillator to switch frequency sources in a safe manner without introducing glitches.

In addition to the basic frequency output, 8N3DV85KC-0056CDI8 provides an enable output, a programmable open-drain buffer, and a 500 MHz programmable timer for frequency monitoring. This timer can be set to accurately count the time between successive occurrences of the output signal.

The 8N3DV85KC-0056CDI8 is highly configurable. It has a 4-wire UART serial interface for programming and communication, as well as a range of configuration options for setting the frequency accuracy and other parameters.

Overall, the 8N3DV85KC-0056CDI8 is a versatile programmable timer/oscillator designed to provide long-term accuracy and stability. With its wide range of features, it has the potential to be an ideal solution for a variety of applications.
