Oscillators 

As a versatile device, oscillators are control devices commonly used in electronic circuits. SIT9120AI-2B1-33S156.250000E is one of them. It is a surface-mounted crystal oscillator with various features of high frequency stability and excellent temperature characteristics.

SIT9120AI-2B1-33S156.250000E is suitable for wireless communication systems, mobile electronic communication systems and digital cellular systems due to its excellent temperature characteristics. Widely applied in environment of network communication, automobile navigation system, vehicle audio and compatible with WiFi and CDMA.

Its working principle is through the piezoelectric effect of crystal. A crystal unit is mounted inside a crystal oscillator. When a signal of the required frequency is injected to the oscillator circuit, the crystal starts to vibrate, providing RF signal of required frequency. Such signal can be used for specific purpose such as timing signals.

In an oscillator, a crystal resonator in a circuit containing some feedback circuit is treated as a linear synchronous oscillator circuit. This creates an embedded feedback system for sustaining an oscillation.

The required frequency generated by SIT9120AI-2B1-33S156.250000E is 156.250000E. According to the value, frequency accuracy is 0.45ppm/°C (maximum). In addition, the power consumption is 1.2mA at 2.2V. SIT9120AI-2B1-33S156.250000E uses a miniature SMD package to provide accurate oscillation frequency, high reliability and small size.

SIT9120AI-2B1-33S156.250000E thus proves to be a reliable SAW oscillator with high frequency accuracy and temperature stability, making it suitable for the applications of wireless communication systems, mobile electronic communication systems, digital cellular systems and more.
