Working Principle of 8N4Q001FG-0171CDI8

The 8N4Q001FG-0171CDI8 utilizes a Quartz Crystal Resonator to accurately generate a timing signal. The Crystal Resonator is a fixed frequency component that oscillates when supplied with an electric current. The oscillator frequency is controlled by a range of variable parameters including the crystal’s thickness and surface area as well as the connections to the circuit.

The 8N4Q001FG-0171CDI8 is based on a two-stage clock generating architecture combined with an on-chip oscillator selection circuit. The first stage of the clock generating architecture is a Voltage Controlled Oscillator (VCO) which supplies an oscillation frequency which is adjustable to meet any timing requirement. The second stage is a divider circuit which divdes the VCO’s output frequency by a selectable value. This ensures that the output frequency is accurately determined.

The on-chip oscillator selection circuit enables the user to select from a range of clock frequencies accurately and precisely. The selection circuit comprises of a bank of crystal oscillator circuits which provide a range of output frequencies ranging from 32kHz up to 8MHz. The output frequency is selectable via software, providing flexibility and accuracy.

Conclusion

The 8N4Q001FG-0171CDI8 is a Programmable Timer/Oscillator designed for accurate time measurement applications. It utilizes a Quartz Crystal Resonator and a two stage clock generating architecture to accurately generate timing signals over a range of clock frequencies. With an on-chip oscillator selection circuit, the output frequency can be selectable via software for added flexibility and accuracy.
