Introduction

CE3291-2.048 oscillator is a high precision frequency source used for Professional applications, such as broadcast television, cellular signals, telecommunication, transportation and so on. It is an extremely low power oscillator and uses a low thermal stability crystal for the frequency source of the oscillator.

Application Field

CE3291-2.048 oscillators are used for a variety of applications, including broadcast television, cellular signals, telecommunication, transportation, and many more. These oscillators are typically used as an accurate source for radio transmission and reception, low-noise testing, radio frequency (RF) communication systems, and other applications that require highly precise frequencies.

Working Principle

The CE3291-2.048 oscillator works by using an electrically energized piezoelectric crystal to create a signal at a precise frequency. The crystal is connected to an amplifier circuit, along with a resonator circuit, in order to create an oscillating output signal. The frequency of this output signal is determined by the characteristics of the crystal.The oscillator amplifies the crystal’s weak signal to the required level and then passes the amplified signal to the resonator, which functions as a filter. The resonator produces a tuned frequency, which is then fed back to the crystal. Once the frequency of the oscillation is established, it is buffered and passed on to the user’s application.

Conclusion

The CE3291-2.048 oscillator is an extremely useful tool in many applications due to its low-power consumption, low thermal stability, and highly precise frequency. Its application fields include broadcast television, cellular signals, telecommunication, transportation, and other applications that require accurate frequency sources. It works by using an electrically energized piezoelectric crystal to produce an oscillating signal, which is then buffered and passed on to the user’s application.
