8N3DV85KC-0048CDI Working Principle

The working principle of 8N3DV85KC-0048CDI is that it can maintain a fixed oscillating frequency over a large temperature range by utilizing a digital compensation circuit that uses a temperature compensated external crystal oscillator.

First of all, the digital compensation circuit will use the oscillator signal outputted to latch a duty cycle generated by a programmable pulse stretcher circuit. Then, the output duty cycle determined by the pulse stretcher will be compared with the reference signal of a division counter in the state of a charge pump integrated with an operational transconductance amplifier. Last but not least, the amplified signal will affect the frequency of the oscillator by adjusting the load capacitor of the temperature compensated crystal oscillator.

In brief, 8N3DV85KC-0048CDI works by converting an accurately known external crystal oscillator frequency into a temperature compensated oscillator signal through the combination of a reference and monitoring circuit.
