SIT9120AC-2C2-25E156.250000Y

Oscillators are devices that are used to emit a controlled, periodic signal, typically by a system of electrical components. The oscillators generate a changing electrical signal over time, such as those of the alternating current which are found in household electrical appliances. This changing electrical signal is typically a sinusoidal wave, which means it is sinusoidal in shape. Oscillators are used in a variety of devices, including clocks, stereos, and computers.

The SIT9120AC-2C2-25E156.250000Y oscillator is a 3V quartz oscillator of the 2C2 configuration and 25E156.25MHz type. It is a dual-output oscillator which emits 162.5MHz and 156.25MHz signals simultaneously. The oscillator utilizes an AT-cut crystal and has a very low power consumption and low temperature coefficient.

The primary application field of the SIT9120AC-2C2-25E156.250000Y oscillator is broadcast audio and digital video applications. It is used in devices such as DVB receivers, TV tuners, and other similar devices where both 162.5MHz and 156.25MHz signals are needed. This oscillator can also be used in GSM, cellular and PCS base stations, as well as in EDGE (Enhanced Data Rates for GSM Evolution) radio transceivers.

The oscillator can also be used in 3G (Third Generation) radio systems. In particular, it is used in UMTS (Universal Mobile Telecommunications System) base stations and HSDPA (High Speed Downlink Packet Access) transceivers. Additionally, it can also be utilized in GPRS (General Packet Radio Service) transceivers and W-CDMA (Wideband Code Division Multiple Access) base stations.

The working principle of the SIT9120AC-2C2-25E156.250000Y oscillator is based on the fact that an electrical circuit can be set up in such a way as to generate an alternating current. The circuit creates an oscillating electrical signal that can be applied to the quartz crystal. The quartz crystal then acts as a filter to filter out only certain signals. The oscillator then amplifies these signals and emits them continuously at a constant frequency.

The crystal oscillator itself consists of several components, such as a quartz crystal, an oscillator coil, and an amplifier circuit. The quartz crystal acts as the filter for the signals, while the oscillator coil and the amplifier circuit help to amplify the signal. The oscillator also contains capacitors and resistors which help to shape the waveform of the signal. The signal is then emitted at a constant frequency.

The SIT9120AC-2C2-25E156.250000Y oscillator is a reliable, high-performance device suitable for a wide range of audio and digital video applications. It operates at a frequency of 162.5MHz and 156.25MHz simultaneously and is capable of providing a stable signal over a wide temperature range. The high-performance design ensures high accuracy and good phase noise performance, while its low power consumption makes it a suitable choice for many applications.
