Oscillators are utilized in many applications due to their ability to produce an output signal with a predictable frequency. The CPPFXC5L-A7BR-98.304TS Oscillator is an example of this type of device, and in this article we will discuss its application field and working principle.

The CPPFXC5L-A7BR-98.304TS Oscillator is an oscillator designed for use in a wide range of applications. It is a low-jitter dielectric resonator oscillator (DRO) and is designed for applications where frequency stability and accuracy are important. The device is suitable for use in test equipment, cellular base stations, and other communications systems that require a precise and stable signal.

The CPPFXC5L-A7BR-98.304TS Oscillator features a frequency range of 97.300MHz to 98.500MHz with a nominal center frequency of 98.400MHz. The device has a frequency stability of ±100ppm over the operating temperature range of -20°C to 85°C, and a harmonic suppression of 60dBc. The device has an output power of +13dBm and a phase noise of -121dBc/MHz at offset frequency of 5KHz from its center frequency. The device also has an excellent immunity to power supply noise, with the input voltage tolerance of up to ±12V.

The CPPFXC5L-A7BR-98.304TS Oscillator uses a dielectric resonator as its resonating element. This is a piece of ceramic material with specific properties that allow it to vibrate at a certain frequency. It is composed of metal electrodes on the top and bottom, with the ceramic dielectric in the middle. A drive signal is applied to one of the electrodes and when the frequency of that signal matches the resonating frequency, the dielectric resonator will begin to vibrate. This causes a signal to be generated with a frequency that matches the resonating frequency.

The device also utilizes a phase-locked loop circuit that maintains the output frequency of the oscillator locked to the resonating frequency. The loop takes the output of the oscillator and compares it with a reference clock signal. If the frequency of the output signal deviates from the reference signal, the loop will adjust the drive frequency of the oscillator so that the output remains locked to the reference frequency. This provides excellent frequency stability and accuracy.

The CPPFXC5L-A7BR-98.304TS Oscillator is a versatile device that can be used in a variety of applications. It is suitable for use in GSM, WCDMA, CDMA, and other cellular systems as well as GPS receivers, vocal synthesisers, and any other applications where precise and stable frequency is required. It is an ideal solution for these applications due to its low jitter, excellent phase noise, and wide temperature range.
