The working principle of 8N3DV85FC-0159CDI is based on a patented storage element Referring to Figure 1, the oscillation frequency is determined by an on-chip VCO and a control logic circuit. When power is applied to the oscillator, the control logic circuit turns on the oscillator, allowing the VCO to stabilize and calculate the frequency. To program the oscillator, the user supplies a serial data stream of programmed frequency, often referred to as a serial data stream. Using this serial data stream, the on-chip control logic will configure the VCO’s frequency to the programmed frequency. After the control logic have performed the initial programming, it will continually monitor the reference frequency signals, as well as the VCO frequency, to ensure they remain in sync.
