Oscillators

Oscillators are components capable of providing a periodic electrical signal, typically for the purpose of maintaining a constant frequency level. They are widely used in telecommunication and broadcasting applications where an accurate frequency is required. One oscillator widely used in these applications is SIT1602BC- 13-30E- 72.000000D.

Application Field:

SIT1602BC-13-30E-72.000000D is an oscillator designed for use in the cellular radio frequency bands at 850 MHz and 900MHz which is widely used for voice and data transmission. It is suitable for applications in CDMA and other wireless communication systems. The device is frequency-programmable and offers an easy and low cost solution for mobile phone base station frequency synthesis.

Working Principle:

SIT1602BC-13-30E-72.000000D is based on the PLL (Phase Lock Loop) circuit. This integrated circuit works by comparing two signals and creating a third signal that is synchronized to the frequency of one of the input signals (usually the reference signal).

The input frequencies are usually amplified in the amplifier section, which then feeds a phase comparator. The phase comparator compares the input signals and determines the amount of phase difference between them. This phase difference is used to adjust the output frequency of the oscillator such that it is synchronous with the reference signal.

The oscillator circuit is also equipped with a filter to remove any unwanted signals and ensure that the output signal is free from noise. The output frequency can be adjusted by adjusting the frequency of the reference signal, thus ensuring that the oscillator can be used for applications that require precision frequency control.

Conclusion:

SIT1602BC-13-30E-72.000000D is a highly reliable and cost-effective oscillator that can be used for the applications such as cellular radio frequency bands at 850 MHz and 900MHz. It is suitable for use in all cellular networks and offers an easy and low cost solution for frequency synthesis. The oscillator works by using the PLL (Phase Lock Loop) circuit where the output frequency is adjusted by adjusting the frequency of the reference signal.
