Oscillators

An oscillator is an electronic circuit that generates a periodic, oscillating electronic signal, often a sine wave or a square wave. Oscillators convert direct current (DC) from a power supply to a signal of a specific frequency and amplitude. Oscillators are widely used in electronic systems for signaling, timing, and many other applications. Among the numerous types of oscillators, one of the most popular is SIT1602AI-72-25S-24.000000D.

SIT1602AI-72-25S-24.000000D Application Field

SIT1602AI-72-25S-24.000000D is an analog voltage-controlled crystal oscillator (VCXO) designed for demanding applications requiring high performance and tight phase noise control. It offers high frequency stability of 0.2ppm, low phase jitter of 0.5ps, and wide tuning range of ±2.5ppm.

SIT1602AI-72-25S-24.000000D is suitable for applications in communications, instrumentation, computer equipment, audio, and automotive sectors. Examples of typical applications include timing/clock oscillators, reference clock sources, clock synchronization, mobile phase, audio signal generation, and synchronization of data and radio signal.

SIT1602AI-72-25S-24.000000D Working Principle

The SIT1602AI-72-25S-24.000000D consists of a voltage-controlled crystal oscillator (VCXO), a temperature-compensating oscillator board, and a frequency control device, such as a phase-locked loop (PLL). The PLL adjusts the frequency or phase of the output signal according to the input signal. The main difference between a VCXO and other oscillators is the ability of the VCXO to accurately control the output frequency by changing the applied voltage.

In the case of the SIT1602AI-72-25S-24.000000D, the crystal oscillator is placed on the board and a temperature-compensating oscillator is connected to the board. The frequency control device is designed to adjust the frequency of the output signal so that it is equal to the input signal or within close tolerance. When the applied voltage is changed due to temperature variation or other external factors, the output signal is automatically modified to match the input signal.

The SIT1602AI-72-25S-24.000000D has wide temperature range of -20℃ to +70℃ and is capable of reducing phase noise down to –165dBc/Hz at 10kHz offset. It also features low jitter of 0.2ps to 70ps and excellent stability of 0.2ppm over the -20℃ to +70℃ temperature range.

In summary, the SIT1602AI-72-25S-24.000000D voltage-controlled crystal oscillator (VCXO) provides excellent performance for demanding applications such as communications, instrumentation, computer, audio, and automotive applications. It delivers high frequency stability, low phase jitter, and wide tuning range.
