Working Principle

The ABLJO-122.880MHZ-T2 oscillator uses a quartz crystal as its main resonating element, giving the oscillator a stable and precise frequency. The quartz crystal is connected to an impedance transforming buffer stage, which has a low impedance output and a high impedance input. This buffer stage amplifies the current output from the crystal, and provides DC voltage isolation, preventing interference from the external circuit. The amplifier stage is driven by a current source providing a constant current, thus assuring a constant amplifier gain throughout the temperature changes. The output from the amplifier is fed back to the input of the crystal circuit. This feedback signal is filtered to get rid of noise and then amplified in order to increase the power level of the signal. The output of the oscillator is then taken from the output of the amplifier, and is filtered to remove any unwanted frequencies.The ABLJO-122.880MHZ-T2 oscillator provides low power consumption, high frequency stability, and very good temperature stability over a wide temperature range. The oscillator also provides excellent phase noise performance, as well as a very low EMI emission from its enclosure. The oscillator\'s high degree of accuracy, combined with its low power consumption make it well suited for use in a wide range of applications.
