Oscillators

An oscillator is a circuit that generates repetitive electronic signals as its output. These signals are usually in sine, square, triangular, or sawtooth waveforms. Oscillators are used as a source of high-precision timing signals, as a source of signals to modulate other waveforms, and in radio communication systems for radio frequency transmission. In this article, we will discuss one particular oscillator, the SIT1602BC-32-28E-66.666600Y, and discuss its application field and working principle.

The SIT1602BC-32-28E-66.666600Y oscillator is a Clock-PLL-based crystal oscillator designed for general purpose usage in multiple industries, mainly focusing on telecommunications, broadband technology, security systems, industrial control, automotive applications, and RF/microwave communications. With a frequency range of 16.777216 MHz to 240.000000 MHz, this oscillator is designed for temperature stability, long-term aging, and low jitter performance. It is constructed with a minimum of two stages of PLL, an output buffer, a crystal, a loop filter and a voltage-controlled oscillator, yielding excellent performance at wide-ranging frequencies.

The working principle of the SIT1602BC-32-28E-66.666600Y oscillator is quite simple. The circuit begins with the crystal, which vibrates and produces a periodic signal. The periodic signal is then processed by a PLL (phase-locked loop) stage, which ensures that the output signal is at the specified frequency and has low jitter. The output of the PLL stage is then further buffered to stabilize the signal and provide consistent output. The output of the buffer then goes through a loop filter that filters out noise before being passed through a voltage-controlled oscillator. The voltage-controlled oscillator is the last stage in the circuit and is responsible for producing a signal that is precisely in line with the frequency of the crystal.

In summary, the SIT1602BC-32-28E-66.666600Y oscillator is an excellent choice for any application that requires precision frequency control. Its wide frequency range, low jitter performance, and temperature stability make it an ideal solution for many industries. Its simple construction and working principle make it a reliable and cost-effective choice as well.
