Oscillators

Oscillators are electronic components designed to achieve operations that require periodic electronic signals. They are used in a wide range of applications such as communication systems, timekeeping, and measurement, among others. SIT1602BC-11-18E-40.500000E is one of the oscillators available in the market and it comes with its own application field and working principle.As a stable voltage-controlled oscillator (VCO) with good frequency stability, the SIT1602BC-11-18E-40.500000E suits numerous applications found across various industries. This includes radio frequency, cellular communications, image processing, and medical imaging, among others. Its features make it suitable for those applications in need of highly reliable and stable oscillation. For instance, with typical low phase noise of -93.9 dBc/Hz, the oscillator can achieve low spurious signals and interference from other signals. Similarly, its low current consumption of 5.2 mA from +5 Vdc makes it a good fit for those applications concerned with power efficiency. As far as the working principle is concerned, the oscillator uses a voltage-controlled oscillator circuit in combination with a phase-locked loop (PLL) to achieve the desired oscillation frequency. This circuit is formed by several active and passive components. First, the active components include an operational amplifier (Op Amp), a voltage-controlled oscillator (VCO) circuit, and a comparator. All these components are connected together in such a way the input signal is equalized with the output of the VCO within a precision of +/- 5%. This then allows the oscillation to be set and controlled to achieve a desired frequency range of 40-500 KHz.The passive components that make up the SIT1602BC-11-18E-40.500000E oscillator comprise resistors and capacitors, which act as voltage dividers and AC coupling capacitors. These elements enable the input signal to be changed to a desired range of frequency and also to provide the PLL with the necessary input signal for locking the frequency of oscillation.Finally, the oscillator is also equipped with temperature compensation and trimming capability, in order to achieve the frequency stability. The temperature stability ranges from 25ºC to 85ºC and the cycle-to-cycle stability ranges from 0.08µs to 0.3µs. The trimming also ensures that the desired output frequency can be achieved even if the temperature varies.In conclusion, the SIT1602BC-11-18E-40.500000E oscillator is a reliable and stable product with a wide application field and a well-structured working principle. Apart from the wide frequency range and stability features, it also has a low current consumption, which makes it ideal for applications where power efficiency is a priority.
