Oscillators

An oscillator is a device that produces periodic, oscillatory electronic signals. Oscillators are fueled by an outside energy source, and convert this energy source into a functional output signal. Oscillators are encountered in a wide variety of applications, from music synthesizers to microprocessors.

One such oscillator is the SIT1602BC-83-33E-75.000000Y, which is precisely designed to convert a specific frequency input (in this case, 83MHz) into a stable clock signal, allowing it to be used as a timing reference for various devices. This oscillator is designed as an energy-saving oscillator (ESO), meaning that it is powered by the direct current (DC) input voltage, but the oscillation frequency is digitally controlled by short, low power pulses of the external voltage. Using a crystal of quartz, which vibrates when excited at a specific frequency, is a cost effective way to obtain a stable and accurate frequency output.

The working principle of this oscillator is relatively simple. First, the crystal is excited at a specific frequency and starts to vibrate sympathetically. This sympathetic vibration absorbs the available energy, which results in a fixed frequency. The energy stored in the crystal is transferred to the output of the crystal oscillator, resulting in the division of square wave signal or pulse wave signal. The power transfer from the quartz to the output of the device is done through the mechanical oscillator, which is mounted directly on the quartz crystal.

This oscillator is mainly used in communication systems, such as in base station applications in mobile networks, wireless LAN applications, and GPON systems., as it has relatively good phase noise performance. This oscillator is also used in a wide variety of other systems that require oscillators that have low output power consumption and better jitter performance, such as in radio transmission circuits, FM broadcast stations, and aerospace applications. Besides, it can also be used as a local oscillator in radio receivers and ICs for clock signal generation.

In conclusion, the SIT1602BC-83-33E-75.000000Y oscillator is a cost effective device, designed to convert a specific frequency input into a stable clock signal. It is mainly used in communication systems that require low output power consumption and better jitter performance. The working principle of this oscillator entails the absorption of available energy from the quartz crystal, which causes the crystal to vibrate sympathetically and consequently transferring the energy to the output of the device.
