Oscillators play a key role in many modern electrical and electronic systems. They are used in the construction of electronic circuits to generate and sustain a specific oscillatory signal in a controlled frequency range. One particular type of oscillator is an SIT1602AC-13-25E-50.000000E oscillator. The purpose of this article is to discuss the application field and working principle of this type of oscillator.

Application Field

The SIT1602AC-13-25E-50.000000E oscillator is a multi-function, temperature compensated oscillator that is well-suited to applications requiring accuracy and stability over temperature range. It is a low-noise oscillator that can be used for the generation of high frequency signals in a wide range of applications. Examples include crystal, MEMS and SAW based oscillators that are used for resonator elements in filters, frequency dividers and as input to phase locked loops (PLLs). Additionally, these oscillators can be used in control/timing circuits for precision clock generators and in paging receivers.

Working Principle

At the heart of the SIT1602AC-13-25E-50.000000E oscillator is its variable tuning element, which is a combination of two voltage-controlled oscillator (VCO) networks. The primary VCO is the main tuning element and it is composed of two analog quartz crystal circuit blocks which are connected in parallel and sandwiched between two amplifiers. The resonant frequency of the primary crystal is controlled by the software programmable frequency parameters. These frequency parameters include the primary crystal frequency, the reference crystal frequency, and the circuit parameters determined by these two frequencies. The main tuning element is then adjusted by using a digital or analog voltage control, which allows the oscillator to form and track its resonance accurately and quickly.

The SIT1602AC-13-25E-50.000000E oscillator also incorporates a temperature compensation element. This element uses a temperature sensor and a software decoder circuit to generate a digital control signal. This control signal is used to adjust the resonant frequency of the quartz crystal circuit, allowing the oscillator to remain stable over the temperature range specified in its data sheet. This temperature compensation feature is particularly important in applications such as the control/timing circuits for precision clock generators where the clock frequency must remain stable over a wide temperature range.

Furthermore, the SIT1602AC-13-25E-50.000000E oscillator is designed with a reference compensation circuit. This circuit is used to prevent frequency drift caused by the aging of the reference crystal due to environmental or electrical changes. The reference compensation circuit adjusts the resonant frequency of the reference crystal in order to maintain the frequency stability of the oscillator.

In conclusion, the SIT1602AC-13-25E-50.000000E oscillator is a multi-function, temperature compensated oscillator that is well-suited to applications requiring accuracy and stability over a wide temperature range. It is designed with a variable tuning element, temperature compensation element and a reference compensation circuit which ensure that the frequency of the oscillator remains stable over its specified temperature range.
