Pin configurable/selectable oscillators have become a popular choice for many applications due to their flexibility, wide frequency range, and cost-effectiveness. These types of oscillators are typically identified by their model number such as 554CD000130DG. Oscillators from this family are commonly used in various communications, industrial, medical, and automotive applications.

The 554CD000130DG oscillator is a hybrid quartz crystal oscillator (VCXO) and is available with an adjustable frequency range from 10 MHz to 24 MHz. It is temperature-compensated and temperature-controlled, meaning it can remain stable over a wide temperature range to provide reliable performance. This oscillator is also pin configurable, meaning it has two terminals for controlling the frequency by varying the voltage in either one of the pins, making it ideal for frequency selection and tuning.

The working principle of the 554CD000130DG oscillator is based on crystal oscillator technology. When an alternating current (AC) signal is applied to the crystal, it vibrates with a characteristic frequency. This frequency is determined by the physical properties of the crystal, such as its plate width and plate length. The amplitude of the oscillation is determined by the resistors, capacitors and inductors connected to the crystal. When current is applied to the oscillator, an inductor is used to transfer the current to the crystal, and then the capacitors filter the signals. The resistors act as current-limiting devices and serve to protect the crystal from damage.

The frequency of the 554CD000130DG oscillator can be adjusted by adding voltage to either the V0 or V1 terminal. For example, increasing the voltage on the V0 terminal will increase the frequency of the oscillator, and decreasing the voltage on the V1 terminal will decrease the frequency. This adjustment process is referred to as pull-in voltage control and is used to tune the oscillator to an exact frequency. The frequency of the oscillator can also be adjusted by changing the capacitance load on the crystal. By adding or removing capacitors, the frequency of the oscillator can be ramped up or down, respectively.

The 554CD000130DG oscillator has proven to be an effective and reliable tool for a wide range of applications. These oscillators are well-suited for use in communications, industrial, medical and automotive applications due to their temperature stability, wide frequency range, and cost-effectiveness. The effective use of pin configuration and pull-in voltage control also makes this oscillator an effective choice for frequency selection and tuning.
