Oscillators provide a periodic signal, usually used to generate frequency, in order to maintain stability in circuits and systems. The XG-2121CA 200.0000M-LGPNB is an oscillator that operates at frequencies up to 200 MHz. It utilizes a number of technologies that help to attain this high frequency level, such as Low Phase Noise Oscillator (LPNO) and Digital Frequency Synthesis (DFS).

The XG-2121CA 200.0000M-LGPNB is typically used in a wide range of different applications, including communications, military, and aerospace applications. It is commonly found in Embedded Base Stations (EBS), Mobile Base Stations (MBS), Radio Frequency Identification (RFID) systems, Global Positioning System (GPS) receivers, avionics, power converters, and space and satellite communications, as well as many other applications. It is also a popular choice for applications which require small size and low power consumption.

The working principle of the XG-2121CA 200.0000M-LGPNB is based on phase-locked-loop (PLL) technology. PLL is a closed loop control system that uses a phase comparator to compare the phases of two input signals. The output signal of the phase comparator is used to control the oscillation frequency of a voltage controlled oscillator (VCO). The input signal to the phase comparator is provided by a reference oscillator; usually a quartz crystal oscillator. The frequency of the reference oscillator is seen as the control signal to the internal voltage controlled oscillator. The output of the voltage controlled oscillator is then feed back to the phase comparator. This output is compared with the signal from the reference oscillator in order to maintain its phase.

The XG-2121CA 200.0000M-LGPNB also utilizes Low Phase Noise Oscillator (LPNO) technology to obtain a low phase noise signal with a high signal-to-noise ratio. The LPNO is constructed from a two-stage amplifier made up of an oscillator and a degradation part. The amplifier provides a high-frequency sinusoidal signal to the voltage controlled oscillator. The low phase noise output is obtained from the combination of the oscillator and degradation stages.

The XG-2121CA 200.0000M-LGPNB also utilizes Digital Frequency Synthesis (DFS) technology, which controls the internal voltage controlled oscillator to output a stable sine wave signal. The Digital Frequency Synthesis technology enables the oscillator to have an adjustable frequency range. The frequency of the oscillator can be changed by the addition of digital words in the control registers, which allow the VCO to be tuned in steps of 1 Hz.

With the combination of Low Phase Noise Oscillator and Digital Frequency Synthesis, the XG-2121CA 200.0000M-LGPNB provides a reliable and low phase noise source, and is suitable for high-precision and high-performance applications. The output of this oscillator has a low phase noise of -80 dBc/Hz at 10 kHz, and a high signal-to-noise ratio of up to 103 dBc/Hz, making it an ideal option for applications that require low noise output such as communications, military, and aerospace applications.
