Pin configurable/selectable oscillators are electronic devices which use a variety of electronic components to configure a frequency of oscillation. In this case, the 534KC000738DGR is an example of such an oscillator. It is an ultra-low jitter oscillator which uses a load capacitance of 5pF, an ESR of 10kOhm, and an adjustable oscillation frequency range of 2MHz to 5.2MHz.

The 534KC000738DGR oscillator is also capable of providing multiple outputs such as LVPECL/LVDS, S/DCLK, and HCSL, which makes it well suited for use in applications where precise, low noise digital clock signals are required. The device features a total input enable function, which allows for simultaneous operation of two separate clock outputs.

The working principle of the 534KC000738DGR is simple. It works by using a crystal oscillator circuit comprising of a fixed capacitance, a voltage-controlled resistor, and an oscillator element. The voltage-controlled resistor is connected to the oscillator element to adjust the frequency of the oscillation. When the frequency is changed, the oscillator element excites the crystal and the crystal produces an oscillation signal whose frequency is proportional to the voltage changes in the voltage-controlled resistor.

The frequency of the 534KC000738DGR is set using a PMOS/NMOS network, which is used as an active load to adjust the oscillation frequency. This can be done by adjusting the values of the loads connected to the oscillator element. The output of the oscillator can be further tailored to achieve the desired performance characteristics such as jitter, rise and fall times, and skew.

The 534KC000738DGR can be used in a variety of applications. It is ideal for communication links and network synchronization clocks, jitter attenuator applications, serial transmission timing clocks, as well as video processing systems. It is also suitable for use in precision frequency measurement applications and waveform generators.

In conclusion, Pin Configurable/Selectable Oscillators like the 534KC000738DGR use dual active loads, a crystal oscillator circuit, and a voltage-controlled resistor to configure a desired frequency of oscillation. The device features outputs like LVPECL/LVDS, S/DCLK, and HCSL and can be used in applications where precise, low noise digital clock signals are required. By adjusting the loads, the output of the oscillator can be tailored to achieve the desired performance characteristics.
