Working Principle

The IDT 8N4DV85AC-0094CDI8 timing device uses programmable PLL-based technology for improved clock jitter performance and optimized frequency accuracy. It is a single-chip solution, which comprises of a programmable oscillator, crystal oscillator, and external reference input. This ensures that the chip can generate the required signal with great precision.

It achieves this through several stages. It starts by converting the reference clock into a digital signal using an analog-to-digital PLL. It then converts this digital signal into a voltage signal, which is converted into a multiplexed signal. This multiplexed signal is then sent through a digital-to-analog-PLL loop filter, which further reduces ripples while amplified to achieve greater accuracy. Finally, the signal is delivered to the output buffer, where it is outputted as a digital signal at the adjusted frequency settings.
