Oscillators are widely used in industrial automation, communications, precision agriculture, medical treatment and other fields, and the SIT1602BC-71-28N-20.000000D oscillator is no exception. The SIT1602BC-71-28N-20.000000D is a voltage controlled crystal oscillator (VCXO) that uses a digitally programmed microprocessor to latch an external tuning voltage to a reference voltage to control the output frequency. With excellent stable, low jitter, and wide programmable frequency performance, it is widely used in base stations, satellite communications systems, high-end storage devices, etc.

The SIT1602BC-71-28N-20.000000D oscillator has five control parameters, the output frequency (FREQ), voltage tuning frequency (VTF), temperature compensation value (TCV), frequency modulation depth (FMD), and pullability frequency (PBF). It also has three temperature ranges, -40°C to +85°C, -40°C to +110°C, and -40°C to +125°C. The SIT1602BC-71-28N-20.000000D oscillator has a working current of 28mA and an output voltage of 1.8V. It achieves a frequency stability of 0.02ppm, and jitter performance of 10-12ui.

The working principle of the SIT1602BC-71-28N-20.000000D oscillator is based on the use of a standard quartz crystal and a control circuit. The quartz crystal is connected to a tuned circuit that consists of a series RLC circuit and other components. By applying an appropriate voltage to the control circuit, the frequency of the oscillations can be tuned. This voltage is called "tuning voltage". The tuning voltage is then compared with the reference voltage of the applied controller. If the tuning voltage is higher than the reference voltage, then the frequency of the oscillations will increase; if it is lower than the reference voltage, then the frequency of the oscillations will decrease.

Furthermore, the tuning voltage that is applied to the control circuit is predetermined by the microprocessor that is integrated into the oscillator. This microprocessor is programmed to latch the external tuning voltage to a reference voltage for a predetermined time (usually set by the oscillator supplier). This allows the oscillator to achieve a precise and stable output frequency by eliminating drifts due to temperature changes.

The SIT1602BC-71-28N-20.000000D oscillator offers a wide range of applications. For example, it can be used for frequency synthesizers and modulators for base station and satellite communications systems. It can also be used for storage devices such as hard drives, optical drives and flash memory devices. Additionally, due to its low power consumption and wide temperature range, it can be used in industrial automation and precision agriculture applications.

In conclusion, the SIT1602BC-71-28N-20.000000D oscillator is a versatile VCXO that can be used in a variety of applications. With its excellent frequency stability, low power consumption, and wide temperature range, it is an ideal choice for a number of applications. It can be used in frequency synthesis and modulation systems, as well as in storage devices and industrial automation applications.
